I would be against no-question-pointers text. It is perfectly ok for a
(authority, cache) server to compress to the question section. The
server can determine if it wants to do so (and if that smashes case).

If you feel the need for text:
Please note that the copied query name can differ in upper and lower
case, and therefore its use as a compression target depends on the
servers choices regarding compression.

Advancing 'copy the question section into the reply bit-for-bit' is fine
with me.
