Re: [webauthn] Plumb User ID through

@christiaanbrand Anyone with physical access to the authenticator can pretend to be any RP, and if they can also convince the authenticator that they're the user (trivial for second-factor authenticators), they can get the user ID for that RP out.

I'm not *certain* that's a leak we should worry about, but we should decide whether to worry about it, and we should probably mention it in the privacy considerations section anyway.
