Sidewalks, unless they are physically separated in some way are an integral part of the highway. Sidewalk tags can allow a router to, maybe prefer, roads with sidewalks but there a lot of cases where this would just be plain annoying. A pedestrian simply needs to be told to follow the road, they are quite capable of deciding which side to walk, where to cross and whether it is simply easier to walk on the road. Mapping sidewalks separately will result in routing to junctions, which are the worse place for crossing the road, or am I expected to connect the sidewalk to the road every metre or so to allow real world pedestrian routing?
