basically your are suggesting cycleway=track for sidewalks. This works
up to some extend, but is not suitable to indicate more then whether
there is a sidewalk (and on which side) or not.

The main purpose of detailing sidewalks is IMHO to be able to add
further details, which might be interesting for the users of the
sidewalk. This could be obstacles (barrier) or narrow stretches of the
sidewalk, where for instance a wheelchair could not pass. Or it could
be details about the sidewalk itself (surface), or details to enhance
the rendering (e.g. in higher zoom levels). It could also be a means
to indicate the position of lowered kerbs, separations between the
sidewalk and the road, etc.

All of these details are not possible to enter following this
proposal. As soon as you tried to enter more detail (using complicated
tags like sidewalk:width:right=0.7m) you will have to split the
street-highway even if it is not concerned itself, because of surface
changes or width changes on one of the sidewalks. This will on the
long run result in very complicated/intransparent structures and many
short pieces for the road.

I discourage you to map them like this.

cheers,
Martin
