I was thinking that, not easy but important.  We do need to do this, just not so that it breaks normal pedestrian routing.

I guess the things that need mapping are: 
drop kerbs - Probably a highway node,  sidewalk:drop_kerb=left/right/both. We will need to map driveway drop kerbs too as these will be crossing point too. 

width - very important as many sidewalks are singlefile for walking.
sidewalk:left:width=0.6, or 1.5 etc

 kerb height - Again important,  different heights are barriers for different people, different wheelchairs.  sidewalk:left:kerb_height=10 cm.
