Re: [webauthn] Multiple Authenticator Options and Policies (#1601)

Yes, RPs typically do not dictate what kinds of UV the user may use, rather the user may choose through their choice of authenticator. The RP may limit the user's options by enforcing an attestation policy of acceptable authenticators. Apart from that, might your UV method concerns be covered by the [`uvm` extension](https://www.w3.org/TR/2021/REC-webauthn-2-20210408/#sctn-uvm-extension)?

PIN policy seems to me like it's also best handled via attestation policy, as attestation would be required anyway for the RP to trust that the authenticator honestly enforces the PIN policy. For example, I think FIDO certification requires some level of PIN complexity enforcement.
