Many transit routing services use the GTFS standard for transit, which includes bus stops placed at the side of the road, not directly connected to any road line features. The routing engine just has to find the closest point on the transit routing graph by following highway=* ways.
Consider also how you would route someone from a amenity=cafe node in a building to a shop=* area in another building across the city, by car. You have to jump from the node to the nearest highway, follow the highways to the other side of the city, and then jump back to the other node. So any router than can handle automobile directions can also manage bus stops or tram stops or platforms at the side of the road, without needing anything other than highway or railway ways and platform or bus stop nodes. I wasn't able to understand enough of the link about updating transit features in Warsaw to see how the stop_position nodes were useful. I understand that some transit agencies provide data about stop positions, and that's the original reason that the stop_position nodes were created. There's no problem with keeping them in your city if you like them, but probably we shouldn't tell new mappers that they are needed, for example in developing cities around the world that currently lack any bus stops. The complexity of the current system, as described on the main pages in the wiki, can discourage mapping anything (for example, I've been discouraged from trying to add any of the minibus routes in my part of Indonesia, since it seemed so complicated to make so many features and routes).
