I don't know what the routers need, to be honest. I have adopted the approach happily because of the frequent two-stage approach. First the main road is mapped with foot/bicycle crossings as nodes , and at a later stage someone else may add the foot/cycleway details - I did not occur to me that there may be an advantage in removing at that stage the already existing crossing node. I would also naively assume, that a car-only router does not need to inspect any of the foot/cycleways in the map, and can use the highway=crossing nodes as an indication to add small delays inthe routing. Anyone in the router business listening in on this conversation?
