Re: [webauthn] more fully delineate "privacy ca", "attestation ca", "anonymization ca" (#1422)

The idea of an anonymous CA that the authenticator uses to generate per request attestations is different from what Google was proposing as a privacy CA.  

The privacy CA was run by the browser and used to blind the RP to attributes of the Authenticator including potentially AAGUID.

They seem quite different to me.  What apple is describing as anonymous is really what Google is doing for  safetynet attestations.   

We never did the privacy CA so getting rid of it is not a big problem.   I just don't think they are the same.
