No, of course not. But they should be things that are of general
utility (we agree that most people will want them) and they should be
orthogonal to what we already have (not just a duplication of
something that's present elsewhere).

Well, we shouldn't assume that everyone uses the same queries, or
issues them in the same order, so I think this is pretty speculative.
