Seriously guys, I don't see your problem.

As Jonni (rainisto) says, the device is still unlockable, you just need to use a different way to do it. And you can go back to a previous software release by resetting.

The rationale is also understandable: they wish to give some more protection to 99% of their users (that is, everybody who is not a kernel hacker).

Please respect the decision and have some patience.
