I imagine that virtually all real-world pedestrian ways that are
one-way for pedestrians would be on dedicated pedestrian ways - that
is, highway=footway. If that's correct, oneway=yes can be interpreted
as referring to pedestrians on footways (it looks like osm-carto
already does this?). I struggle to imagine a one-way pedestrian way
that is also open to bicycle riders (dismount still works in this
scheme). Perhaps the only other thing could be highway=path, where
there could be some ambiguity with bicycles. But at least we can avoid
the "street with sidewalk" interpretation. Does anyone have
counterexamples?
