For the specific case of benches, if you care about orientation you
might as well draw a way instead of a node. It's easyer to map, and
less ambiguous (tag name ? value format ? mapper error ?).

One thing the wiki doesn't specify for way-benches is the viewing
direction (left or right of the way). But following the same
conventsion as for water and cliffs, "view on the right" sounds
intuitive. Somebody should check actual usage and update the wiki.

There may be other usecases where tagging the geometry instead of
drawing it makes sense, but I find it unlikely. One counter-exemple is
roof:shape, but it describes a 3D shape, which the osm data model is
ill-suited for.
