I think focusing on the runtime might be missing the point to some
extent. Removing used #include directives from C source files is
generally good practice just for cleanliness, and this is the same
kind of thing. That said, the argument that future changes are likely
to just put the same 'use' directive back seems to me to have some
merit. But we've probably spent more energy debating this than the
topic deserves. It wouldn't hurt to remove these, and it also won't
hurt if we don't.
