That's why I tought I was doing all right putting the details of the stop
on those public_transport=platform mapped as nodes. When there is an actual
platform, I map it separately as a way or an area, which goes into the
stop_area relation.

I don't mind having both. I do mind putting extra tags like name, ref,
operator, network, route_ref, zone on the stop_position nodes. It's enough
to have that information once.

They moved the details to the stop_position, which I don't consider for
processing.

That only works if there is one stop_area relation per direction of travel.
At the moment the wiki states to use a stop_area relation for all PT
related stuff that is near to each other. I need to relate the platform
nodes to the nearby way, sometimes by means of a stop_position node,
sometimes with help of a stop_area relation.
