Relations are great to represent real-world relations that cannot be inferred (reliably) from the other data in OSM. Often a geometrical relation exists, such as a node inside a polygon, but not always. OSM loves to allow things to be inferred from the data, but there is usually a way of entering the attributes/relationships explicitly as well, for the cases where the heuristics fall down. The wiki says about relations: "Relations are used to model logical (and usually local) or geographic relationships between objects. They are not designed to hold loosely associated but widely spread items. It would be inappropriate, for instance, to use a relation to group 'All footpaths in East Anglia'.Why don't PT stop_areas fit with this?
As all items have co-ordinates, OSM is geospatially aware; and of course any objects with the same value tags are already 'collected together' & searchable.
'stop_areas' - Bins are irrelevant to routing from A to B. Do any routers use them?
