Now, there's things that are left unanswered for now. Can you uninstall Play Services with an already used account? Can you run adb somehow before the phone boots up for the first time, so you can make sure you have a 100% clean Android session? Can you automate the deletion every time you add an account, particularly with guest accounts? Is there any hidden backdoor I have yet to notice?
This is still amazing though, mind you
