Re: [webauthn] attachment is only explicitly used in create()

I vote (a) and I agree with @emlun that this doesn’t work for resident credentials, but it doesn’t need to. This is to solve for a typical reauth scenario where the RP only want to register a credential on a local “platform” authenticator since part of the security model is the fact that the authenticator is built-in (ie. it’s really used as a 2nd factor; the cookie identifying the platform is the first factor). In this case the RP will always have the credentialID since it has a handle to the device (via a session cookie, etc) and can use the allowList.
