Case 1. sounds ok to me, there can always be a reason for a mint to want to restrict access only to certain users. Case 2 would go little bit too far for me, even if exchanges demand it, it still doesn't mean that a privacy activist should comply proactively and add support for this at the protocol level, even if its optional.

2. more general functionality to perform kyc / aml procedures at the protocl level?
