I use QTYPE=ANY for testing and troubleshooting quite frequently, and would
prefer to see it hidden behind an access control mechanism rather than
disabled completely.


(As an aside: I've often wondered why the DNS doesn't have *more* meta-query
types, less extensive than ANY, such as a single type covering A and AAAA.
Or, an EDNS OPT mechanism to request a list of desired types in addition to
QTYPE to be returned in the additional section (subject to packet size, rate
limiting, DNS cookie authentication, whatever).  I would guess the absence
of such conveniences to be the reason Mozilla decided to take their
regrettable shortcut.  It seems like such an obvious optimization, I'm
guessing it was talked to death before I ever started working with the DNS
and there were good reasons not to do it, but I don't actually know what
they were.)
