Alternatively I can imagine having the kerbs modeled as ways as well, and model the true topology (i.e. the highway=footway in the centre of the footway/sidewalk). This way you could use area-relations (type=area) to make actual area:highways for the road (from kerb to kerb) and the sidewalks (from kerb to the border), hereby having an additional benefit. The mapping as shown in the problem description is definitely wrong, considering the conventions we use (highway-ways are in the centre of the highway, hence their crossings cannot be the kerbs).
