User OpenID URI page could be shorter/smaller/lighter
I noticed it take a very long time to sign-in using the GNUSocial OpenID URI (domain.name/user) compared to using other services. I detected this while implementing a consumer (relay agent?) for Gitea. Looking at the logs of one other consumer (Friendica) I realized that everytime the consumer wants to discover the provider endpoints from the page it needs to have the whole user profile page rendered, which contains a lot of other information about the user, including his newsstream.
Maybe there's a way to improve things, like allowing the existance of an openid-specific URL that just gives the metadata ?
