May be you are confusing fingerprint based authenticators with user-verifying based authenticators. user verifying authenticators also consists of authenticators which are local PIN based.

I *believe* understand the UV/PA/RK properties well enough.

My point is more that the API does not allow us to distinguish PA/RK for existing registrations, especially if we did not save transport data. So if we wanted to enforce UV+PA for new registrations, we wouldn't know which old registrations satisfy it.
