I concur, I had come to essentially the same conclusion after discussions with IANA. The registry we were looking for was the one Dave had proposed that has not yet been created.
I can sync with Dave. It might well be that what we want is a sub registry of the form _smtp._rpt. That way the reporting info for any protocol can be discovered with no need to obtain a per service registration.
