I am the mapper. I use the processing to assist me, like a tool. I also try
to map them all in the same way for consistency. The problem is that
apparently there was still room for interpretation in the 'version 2' of
the public transport scheme.

What I see happening in Germany is that information is duplicated
needlessly. Moving it to the stop_area relation would be a logical step,
but information doesn't cascade through like that in OSM. In Belgium every
stop has its own ref, and of course if you calculate a route_ref from the
schedules this will not always yield the same result for both sides of a
street.
