OIDC issuer should return metadata regarding its identity

[besteves4]

Hi. I have been reading the Solid-OIDC and Solid-OIDC Primer specifications and I don't find any information regarding the solid:oidcIssuer information that should be publicly available. I think it would make sense to specify that a request made to the solid:oidcIssuer URI should return information on the identity of the issuer, e.g, the entity responsible for the domain, the entity responsible for hosting, contact information, privacy policy, terms & conditions, what data is necessary to create a WebID (email account,...) and so on.
