Stock rom that doenst loose my bootloader unlock?

Hey guys i was just wondering if there was any way to flash back to stock without loosing my bootloader unlock?
the only way to re-lock the bootloader is by using the fastboot command for it.
This is an interesting question.
I am currently on the latest 4.4.4 and now I would like to try CM 12.x (5.1.).
In case I do not like 5.1, how do I get back to stock without losing the unlocked bootloader?
flashing back to stock will not relock your bootloader. the only way is by fastboot command. so if you an unlocked bootloader there is no need to worry about losing that. you will however lose root which is easy to get back.
