The only thing I have found that implies NOTIMP doesn't apply to queries
for unknown RR types is in RFC 4074, "Common Misbehavior Against DNS
Queries for IPv6 Addresses":
4.3. Return Other Erroneous Codes
Other authoritative servers return a response with erroneous response
codes other than RCODE 3 ("Name Error"). One such RCODE is 4 ("Not
Implemented"), indicating that the servers do not support the
requested type of query.
But I guess that NOTIMP *would* be an appropriate response if the request
is for an unknown QTYPE between 128 and 255.
