Scenario. You need to surrender your device for forensics / cloning / law enforcement (the exact nature is in important, my point is there is some reason to give up your phone in an unlocked state. )
A feature would be good to be able to auto logon of all accounts when the profile unlocks ( the accounts in the setting menu) so if you are signed in to a password manager / messaging service , access to it is revoked.
Not sure how easy that would be to implement and also would like grapheneOS's opinion this as an idea.
