To make my position clearer, the SHOULD here says that a client is not
conforming if it doesn't send the LIST EXTENSIONS without a very good
reason. But if it doesn't need the results, there's no good reason, while
if it does then the SHOULD doesn't do anything anyway.

This doesn't seem to me to be an area that justifies the coercion of a
SHOULD.
