Re: [webauthn] backup states in authenticator data (#1695)

The platforms might decide whether the new device is capable of restoring the backup credential? Is there any policy for this?
RP might want to enforce 2FA (with UV) and so it requires UV for the registration/authentication. If the generated credential is BE (backup eligible) and then restored from the new device, then still we can make sure that the credential is protected by UV? Or, is it possible that the credential is restored but the UP is only supported on the new device?
