[OSM-dev] public transport stop_area relations: have you implemented for routing or another purpose?

[Joseph Eisenberg]

I'm trying to find out if the type=public_transport +
public_transport=stop_area relation or *=stop_area_group relation is
used by any developer or database user.

These relations are supposed to group together features like all the
platforms in a bus station or train station. However, it seems like
these relations may not be necessary or useful for routing
applications.

Has anyone looked into them or know of any current use cases?
