Will they ever be available to OEM unlock?

Sadly no, they never will. And I feel your pain. I had a Note 10+ that I would have abused the **** out of if it had an unlockable bootloader.

I came across a defcon presentation called,
"Breaking the Android Bootloader on the Qualcomm Snapdragon 660".
It would appear that it is certainly possible to bypass a locked bootloader, Two interesting methods that were mentioned,
"The most commonly used approach is to access Qualcomm Emergency Download mode. This is a low-level emergency state boot mode, where diagnostics tools can be used to upload a signed “loader” payload to the chip, which can be used to modify the device’s partitions directly. While this approach is effective, it requires the ability to boot into the mode, which is not always made directly available to users, and access to a signed loader ELF which may not be available for the device.
The second common approach is to attack the device at a hardware level. By disassembling the phone, and connecting to EMMC chip on the board, it is possible to set the “unlock” bit in the configuration partition and gain unlocked access. Public resources exist which outline which pins should be connected to, however this usually requires some hardware knowledge and steady hands. There is also a high risk of irreparably damaging the device."
The rest of the presentation explains how the bootloader lock was bypassed via an exploit.
Ive also heard that exploiting flaws in Qualcomm's chips has become a common way to root bootloader locked devices, If root is all your after.

Since the Galaxy S7. Was able to unlock the bootloader of my Galaxy Note 5, then I looked up info on unlocking the bpooader of the Galaxy S7 and people on the forum for the devi e were saying that it is not possible.
P.S. Sorry for like the month late respone

Has anyone thought that maybe google has made 2.3 unrootable? Scary thought i know, but its kind of like a cat and mouse game with the developers and google/manufacturers with root patches.
Maybe google finally will put the nail in the coffin here?
WOOT. It's rooted, im happily wrong.
It's a developer phone, so why would Google want to make devs waste time trying to root.
could it be possible that Google enable root access by default, then?

Definately not.
Dev phones have always been rootable, i doubt that will change.
The phones that have trouble being rooted are always manufacture customized ones.
it's still able to fastboot oem unlock from what i've heard. Will be rooted same day it's available for purchase guaranteed.

I'd bet that it will be rooted BEFORE!
The developer build on my Nexus One is already rooted. I don't imagine the release build will be any different from all of the previous OTAs.

You are correct.
Samsung never locked their (Android?) phones. Personally I've installed custom ROMs on the Galaxy Spica and international S and both came factory unlocked. Unlike with some of HTC's devices you can flash anything you want without using exploits.

Your right, as of now I don't think Samsung locked any of their phones, but the only thing Samsung has on this phone is the hardware aspect. All the software aspect is by Google.

Then how do you explain threads like this (on the samsung galaxy sub forums):
[HOWTO] [REF] [FAQ] [Guides] [Tutorials] Flash/Root/ADB/ROM [MUST READ!]
It seems like you have carrier/sim lock and root confused. Just like nearly every phone on the market, they are locked. You will also need root to do anything that says "please root your phone". They do not ship this way...
I'm sure it will be rootable... Google doesn't want to block out developers
Just food for thought i guess, we cant know until its released anyways.
What exactly is fastboot oem unlock ?

that's unlocked for carriers with gsm...that's not root. Simply meaning it will work with at&t or tmobile by changing the sim card. Root lets you edit system files and a custom recovery to flash roms
Lmao no one so far in this thread should get one of these developer phones as you plainly do not understand what you are doing here when it comes to deciding what the difference is between root permissions and unlocked to all networks.
lets put it this way, if you are one of the above who are having trouble, dream on and steer clear from the prospects of rooting all together
unless that is you fancy yourself a very expensive paperweight?

This command unlocks your bootloader on the N1/N-S allowing you to flash custom roms, but visibly voids your warranty (bootloader screen shows that it's unlocked)
I don't fully understand the process of unlocking a bootloader on a phone, but what makes a Samsung phone so difficult to unlock? For instance could we unlock this phone using the same method as went use on other phone with a Snapdragon 835 processor?

It's not difficult to unlock, it's impossible to unlock. The team of guys who achieved root access on an SD835 S8 used a root exploit to get root on the phone, the bootloader is still locked and they won't be able to flash anything that isn't signed by Samsung.
As for your second question, ABSOLUTELY NOT.
Each OEM has a different way of unlocking their devices bootloaders.
Sony and HTC email you an unlock code after you submit your IMEI for bootloader unlocking, only with that code you can unlock your device.
Samsung phones (on applicable devices like Exynos ones), simply have a switch in developer options for OEM Unlock, just like Google's Pixel and Nexus devices, once that option is enabled, consider the bootloader 'unlocked', and you should be able to flash whatever you want, regardless of whether it's signed by Samsung or developed by some guy in his moms basement.
TL;DR:
No.

If you're using a phone with an unlocked boot loader could you in theory switch between operating systems? For instance could I flash a rom to run Lollipop on one slot and on another slot run Nougat?

Most phones don't have 'slots'. It's not a common thing yet.
The Google Pixel and Moto Z2 are the only ones that come to mind that have A/B partitions for seamless OS updates and in theory (on a Pixel), one should be able to flash Nougat on Slot A and Android O on Slot B, however I wouldn't recommend it at all, I always like having the same sh*t on both slots.
Also, Lollipop and Nougat are too far apart and there is no device in existence that has its OEM ROM based on LP and N. So no you wouldn't be able to.
Any chance 9f bootloader unlock since the oreo update is out?
Unlikely and so far nothing new indicating it's going to happen.

If someone WAS able to unlock the bootloader, who would be building the roms?
Anyone? A lot of the Exynos ROM's are peoples own projects or unofficial ports of known ROMs, don't know why it'd be any different for the 930U
So did Samsung put the OEM unlock button in Developer Options as a joke? I have a G930T and the switch does nothing but flip back and forth. If i was at Samsung I'd find it hilarious I have to admit

I think oem unlock is suppose to allow your device to not lock to a specific sim card when you insert one
OEM unlock unlocks the bootloader, but only for Exynos chipsets. There is no user accessible way of unlocking a phone from its carrier beyond calling the carrier.
It's present in the snapdragon US models, but does nothing. But that's the fault of US carriers strong arming Samsung into not letting US models be bootloader unlocked.
Is there a way to speak to Samsung officials for them to allow us to unlock bootloader?

Do you think, since a lot has changed then, that there is a version of C.F. Auto root exists for the Binary 10 version of the SM-G930U? went to flash the version for my device from the website and I got the SECURE CHECK FAIL: recovery error, same as if you were installing the wrong firmware for your device... Not quite sure what to do here xD
The model is SM-A015M. It has a Snapdragon processor.
This is a question I tried to solve myself, but I don't know if it's impossible or I'm just dumb and don't know how to do it.
I've followed a lot of guides, a lot of them telling me to do the same:
"Go to Developer Options and enable OEM Unlock, then boot your phone in Download Mode and hold the Volume Up key to unlock the bootloader. Think you did it? No, because Samsung has the Secure boot thingy. So you skip all the setup steps, but remember to connect to a network. After that, enable Developer Options and you should see the OEM Unlock option grayed out."
Click to expand...

And that last part is what ruins everything, OEM Unlock is enabled, but it's not grayed out. Furthermore, I cannot check if the bootloader is unlocked or not via fastboot since I've seen that Samsung doesn't support it. Although, I've used
adb reboot bootloader
which takes me to another screen that obviously says
device state: LOCKED
And I've tried to flash Magisk before with Odin (I don't understand Heimdal fully, to be honest), of course it ended in a failure. I've seen that having a Snapdragon processor makes the bootloader impossible or just very hard (And I'm hoping it's just very hard, 'cause as I'm writing this, it's obviously impossible).
I wonder... If I can't unlock the OEM, why does the developer options give me the choice to unlock or lock it if it doesn't change a thing in the end?

It's not the exact same guide, in terms of words. But I'd be doing the same I did before, so that doesn't work.
sanmsung mobile phones with a that use a snapdragon in north america and south america, and europe that cannot be unlocked
the ones usually sold in asia are the ones you can unlock
and don't even waste more time,samsung took extra steps just so that their mobile does not get unlock and rooted, at least on the snapdragon version
you trip the knox, and prolly will brick your mobile, or at least lose functionality

every Samsung phone that has a snapdragon has a Qualcomm chip as Qualcomm the company makes snapdragon the product.
it's simply not true to say all snapdragon Samsungs can't be unlocked. I'm trying on an unlocked phone now.
it's snapdragons sold in North America and maybe South America (not sure on that last bit) that can't be unlocked.

not really no, unless it's running on a Mediatek SoC (I doubt it and can't be bothered to check)
or there's a serious vulnerability overlooked by the Android devs in both Samsung and Google, you're out of luck
unless of course there's an exploit in the BROM of the SoC, but at this point you're all out of luck since I doubt you'd be able to avoid a softbrick at best and a hardbrick most likely
also I think you CAN unlock the bootloader (OEM unlocking under DevOpts) by giving all your personal data to samsung and google over the span of a week: login to your google and samsung accounts, have a simcard in at all times and be connected to a single wifi accesspoint so that Samsung is absolutely sure of who and where you are
Ok thanks sir

can you send me the link for DevOpts please?
DevOpts is shorthand for Developer Options, on anything past kitkat you get to them by 7 taps on the device build model under device information (every OEM has it placed in a different place) and then going to the developer options screen in the settings (also different for OEMs)
a quick online search should provide you with detailed steps for your device
