I strongly oppose. 2 major issues. 

This is not service discovery this is configuration lookup. The client must have already discovered the oauth issuer uri and the resource uri. 

The objective was to provide a method to ensure the client has a valid set of endpoints to prevent mitm of endpoints like the token endpoint to the resource server. 

The draft does not address the issue of a client being given a bad endpoint for an rs. What we end up with is a promiscuous authz service giving out tokens to an unwitting client.
