"Never" seems a bit strong. If one controls the server being called out to
and knows that the sender doesn't matter to that server's response, then it
shouldn't matter. On the other hand, in that situation, use_sender doesn't
hurt much, either (it may enlarge caches, or I would just say "doesn't
hurt").
