[Tagging] Sidewalks vs Footways

Based on this thread, there seems to be general consensus that the
term "sidewalk" is less linguistically ambiguous than footway.

Where folks are concerned about dual meaning, we can ensure that's
resolved via fixing the wiki, checking JOSM presets, and checking
Potlatch/PL2.

Data consumers who are using either tag should be aware that neither
has been accepted, so they're using it at their own risk.

Josh,

There's nothing wrong, pe se, with that. I've gone back and forth on
whether that's the "right" way to go or not, and I think it's up to
individual mappers, but after considering it, I've decided I prefer
the road to be tagged for the following reasons:

1) It's less ways overall.  That's not normally a consideration I'd
consider important, but in this case, I'd say that the sidewalk is a
feature of the road, and therefore makes the map more useful.

2) Sidewalks are sometimes interrupted, but still logically connected.
An example of this would be a crosswalk. The sidewalk ends, but roads
continues, and the governance of whether a pedestrian can cross can be
placed at the intersection.

3) Making sidewalks a road feature aids the router. It lets the router
say things like "Walk along Main Street".

Individual ways which are unassociated with a road are footways/paths,
and not sidewalks.
