Re: [webauthn] Consider allowing RPs to indicate that they want platform authenticators to be synced across devices

I would recommend pairing such a flag (if we should end up supporting it) with the ability of an authenticator to express support for non-exportable/non-migratable keys in the attestation statement (e.g. similar to never exportable flag in PKCS#11 - but with crptographic assertion on it).
With that RPs interested in the security aspect have an assertion stating whether or not the key is exportable.
