Sure I agree. Though somehow the route needs to have a (logical) stop position, node (as stop): "The order of the members in the relation should be identical to the order in the timetable." Do you agree? But yes - what do you do if a rain route goes through a station, where the rails temporarily split into several tracks? Where is the stop position for that route? Clearly in that case stop_positions on the route cannot be associated with platforms in the station, and full routing is not possible. While it's not possible in general, for some stations (e.g. tube stations), clearly stop_positions could be associated with platforms.
