Before changing the wiki, I'd like a clearer understanding of your proposed
change. As I read this the node is placed on the highway to tell cars that
some type of crossing is located at this node. The crossing way tells the
pedestrian that there is some type of crossing.  With thousands of
crossings already mapped, your proposed change could break routers.
