I don't think those would qualify as "sidewalks" for purposes of this
discussion, since the two proposals both only consider pedestrian walkways
that run along and adjacent to roads.  If a walkway doesn't have those
characteristics, it would just get tagged as highway=footway (probably
with surface=paved), and given a name= only if it has its own, distinct,
name.

This might not be a bad idea.  It makes the association without using a
relation (about which there have been concerns raised regarding the
complexity of handling, both for mappers and data consumers).

I think that the absence of the tag could reasonably be assumed to be
equivalent to "no associated street" but, like oneway=no, it doesn't hurt
to have an explicit value for that case.
