I'm not sure why you consider this a problem?...

Well, we already have a mechanism for making communication protocols in
the Hurd extensible: it's called the RPC mechanism... :-) Let's not try
to invent another generic mechanism on top of RPCs.

*If* ten year down the road we indeed end up with half a dozen
miscallaneous info queries, we can *still* replace them by a new RPC
covering all of it...

Also note that there is precedenct for extending the proc info query by
adding new RPCs.
