The proposal has been discussed in the dnsop group and previous meetings and my
observation of the discussion is that there is both broad agreement that
QDCOUNT > 1 is not used in practice and at least some supporting evidence
presented that it is not observed in the wild either.
I can attest that it _is_ seen in the wild every day in several
customer's networks, but only in form of garbage queries and/or answers.
To the best of my knowledge nothing depends on it.
I wholeheartedly support the draft.
The only piece missing to make it *perfect* is "MUST use QDCOUNT=1", or
in other words, banning QDCOUNT=0 usage with DNS COOKIES. It's
unnecessary complexity.
