The backdoor is already there, is it not? According to Apple's support site, you can remove the lock remotely [1], which means they can remove the lock remotely. You're already trusting Apple.
Given that, removing the activation lock after notifying you with a 30/60/whatever day window to respond seems like a reasonable policy to me.
