that seems like the long way around.

for QTYPE=A, add AAAA as a desired additional data type.

for QTYPE=AAAA, add A as a desired additional data type.

any server which does it will give better time-to-first-ad benchmarks, 
and will therefore outcompete any server who doesn't do it in all bakeoffs.
