First off, I'm not mapping stop_area relations very often, only in case of ambiguity. A stop near to a side street, but the bus passes on the main street, or in bus stations where everything is very near to the other objects.
JOSM's PT_Assistant plugin uses them to figure out which stop_position + way adjacent to a highway=bus_stop node, if they are available. Usually it's possible to determine it geographically. It also only works if the stop_area relation contains pairs of stop_position / bus_stop nodes. If someone simply throws all stop_position nodes, bus_stop nodes and platform ways into them for stops on both sides of a street, or all stops in a bus station, they are useless for that purpose. Since, at that level, I'm using them to pair stop objects, I also have a hierarchy of stop_area relations in some places. (bus stations adjacent to railway or metro stations). At some point I was using stop_area_group for that, but JOSM doesn't recognise that. I don't know of any external app that uses them.
