I'm still fairly strongly opposed for cardinal directions to be applied as
roles to member ways; easier to handle, even with existing tools, to use
child relations with the children having those roles in the super.  Then
all the members of the child relations can just be "forward/backward" as
applicable with "direction=west" or whatever tagged on the relation itself.
