I sometimes tag in this way. The only case I can think of where I do
it is that of motorway_link (or trunk_link, *_link), and in these
cases, I think that a human map reader would usually infer the truth
without requiring visual clues. My reasoning for the explicit tag in
these cases is that some routing engines might consider that a link
(which is usually a ramp) is usually one way, the same way roundabouts
are supposed to be treated.

So for my use, I don't see the need. But maybe there are other cases.
