Why would there be any difference between the two? OpenID Connect does not
dictate where the client metadata comes from.

Per my comments in GitHub, do we want to be able to treat developers of
software that want localhost differently than people that deploy the
software that are able to deploy without registration?

If so, then standardizing how to claim your app may be useful.

There may not be a requirement to actually claim the app though. The
developer might be able to just enter a URI for the client and then have
access to additional features for development. I've not thought through all
the security implications of course!

Sorry we won't see you in Vancouver!
