Because sometimes trams just stop in the road, not at anything that might be described as a platform. The only thing you can see is a pole (looking remarkably like a bus stop, in fact). You could call them railway=platform nodes, but it doesn't sound right. You could call them bus stops, but then they'd render as bus stops. Calling them highway=tram_stop allows the nodes to be used by bus relations, while still using a conventional railway=tram_stop for rendering purposes. > Why replacing the stop position for trams/trains with the platform/pole in > routes? Because the platform/pole is a direct indicator of where the passengers should go to catch the service. The stop position is an indirect indicator of where the passengers should go - ok for simple pairs of tram platforms, but less use for anything else. I struggle to see the value of knowing the stop position except for rendering (it's just the point on the path of the service which happens to be closest to the platform/pole). > > I read implicitly that you agree to use the platform instead of the pole for > relations, correct? > Yes. The things that might constitute a stop (platform, bus_stop, tram_stop, halt, station etc) are all quite distinct from the things that constitute the path of the service. If it stops at a platform, and you have that object available to put in the list of stops in the relation, then I'd use it. > I do not want to obligate someone to tag a stop position.

Tag what you like, as they say, but the route relation should include a clear list of stops. If some people want to use on-the-way nodes as a proxy for the platform (and they do), then having both platforms and stop_positions in the relation strikes me as likely to cause confusion. Better to only put one node (or platform way/area) in the relation per stop.
