Well, a simpler approach is to say that if you ever want to search for
a particular version of any protocol, you can do so using an SQ made
up of the string "version" concatenated with the version number.  We
don't need to provide an e4xhaustive list or anything!

I don't think so.  SQs are still pretty rare in Real Life.
