Very little is actually useless: give us a tool and we'll find a way to use
it, even if that wasn't the intended use.  I'm making no such claim that
you can't do useful things, I'm just saying that the current ones are
*less* useful things from the average author's perspective.  Since neither
of us is "the average author" and we don't have hard data, you can easily
make a counter argument that that's not so.   Let's not do that.  I don't
think it is of critical importance/worth wasting much time debating if we
agree that a 'default' or 'user-agent' value which does the thing it's safe
to say "a lot of authors" (i.e. 100% of the ones I know, which I concede
doesn't constitute an exceptionally large sample set) currently expect is
important/worth taking up.
