[CNAME, "unknown"? Come on.]

It cannot. It would be a serious violation of RFC 3597. I quote it:

   To enable new RR types to be deployed without server changes, name
   servers and resolvers MUST handle RRs of unknown type
   transparently.

And RFC 1035 clearly says:

                2               Server failure - The name server was
                                unable to process this query due to a
                                problem with the name server.

Yes, thre is "a problem for the name server" if it replies SERVFAIL.

Well, it is its entire point.
