I get that but I think OIDC could be extended to cover that too whereas the Authenticator or iDP is the local face scanner kr other biometric and then the rest ie exchange of token etc stays the same. That way there won’t be two completely separate path and that will defeat the purpose of SSO ie OIDC websites will authenticate with google or Facebook but FIDO enabled websites will work with face recognition. And it looks like there are already some implementation of this OIDC enabled face recognition https://www.bioid.com/facial-recognition-app/
