Thank You Sir, I appreciate the confirmation.

I understand that. My worry was not that lock would be force enabled, but that the option would not "ungrey" if I were to choose to lock the bootloader on my N6 again. Either I hadn't paid close enough attention post 7.0 upgrade, or hadn't gone through the 2 step unlock process since running 6.x to notice the option greys out if your bootloader is unlocked on 7.0. I must not be the only one as the description under the option is changed in 7.1 to say "Bootloader is already unlocked" instead of "Allow the bootloader to be unlocked"
Thanks again to you both.
