Probably for the same reason that makes QTYPE=ANY queries very difficult to understand for the beginner and counter-intuitive: because it is hard to specify the semantics. Imagine there is an ADDR meta-query covering A and AAAA. You send QTYPE=ADDR and you get only A record(s). Can you be *sure* (and can you validate with DNSSEC) that there was no AAAA? Think of the various cases, RD=0, RD=1, caches, forwarders, etc. Same question if IETF invents IPv12 and we have AAAAAAAA records. At first, some servers will ignore them. What is the meaning of ADDR if you do not know if the servers handle AAAAAAAA?
