If this were to take the form I described in my original message, 
effectively *all* discovery mechanisms become extensions. The HTTP/HTTPS 
one gets special treatment by getting referenced by a MUST in the core 
spec, but it's still a separate document.

i-names would be handled as part of the "OpenID Discovery for XRI URIs" 
specification I mentioned.
