That changes the intent.  The server that is ultimately contacted
(after all the alt-svc shenannigans) MUST be authoritative for the

Yes, we want to authenticate the alt-svc declaration, but that isn't
actually a necessary precondition on getting what we really want: an
authority for the resource itself.
