Interesting question. Great thinking.

It's done as two simply because I did not know RFC 1035 well back then
(not that I know much more now) and it was fairly easy to code.

Section 4.1.2 does say that there can be up to a 16-bit integer worth of
questions in a request. UDP packet sizes will not be an issue in the new
version.

It would really depend on how well the real-world resolvers responded to
more than one questions.

Hno; EDNS fields were trivial to add as well and close the EDNS bug. I
have some experimental code on west adding them which I can push your
way if you like. Just stupid build errors AFAIK.
