Yes, also immediately thought of all the endless ways this could go wrong and end with someone losing access to their account, which depending on their account could be trivial or life altering, especially if their loss ends up being someone else's gain. Apple takes baby steps so I'm sure this will be limited in nature and most likely will get delayed until fully tested, but I'd definitely avoid testing during betas (with any real accounts that is).
