According to the wiki, public_transport=stop_area is used "to identify
all of the features associated with a public transport interchange or
part of one. A stop area for a simple bus stop with buses in both
directions would consist of two waiting areas or shelters [...] and
two stop positions [...]. More complex stop areas may include multiple
platforms and stop positions and many associated elements."

In contrast, the relation i had in mind would only include one
highway=bus_stop and one public_transport=stop_position. The relation
and the public_transport=stop_position node would only be used for the
rare cases where the stop position cannot be calculated by projecting
the highway=bus_stop node to the highway=* way.
