In fact - what is the point of returning the Question in the DNS

Belt and suspenders perhaps. I would think one or more of the DNS
RFCs would give reasons. If the ID is only 16 bits, it wouldn't
necessarily take all that long to wrap around, and repeating the
question would be a good way to help further protect from a delayed
duplicate of a previous answer - since applications using UDP must be
prepared for their traffic to be lost, duplicated, delayed, bent,
folded, spindled and mutilated...
