I carelessly modified my local fork causing two unrelated commits to be part of this PR. Only commit d7e238e should be part of this PR. If needed, I can close this PR and open a new one. |

Related #1962
#2146 raises the possibility of leaving attestation for all platform authenticators based on the argument that much of the information related to attestation could be re-generated once AAGUID is known (which all platform authenticators keep); however this PR more conservatively only excludes platform authenticators that use self attestation since self attestation does not contain any new information and self attestation is already excluded from being replaced with none when the AAGUID is already all zero (i.e., RPs, even ones that only intend to support none attestations, have to be prepared to handle via error the possibility of receiving self attestation despite requesting none).
The following tasks have been completed:
