there is sometimes another possibility to map detailed areas: maps with
compatible license / open data from the pt operator or the city. Areas are
more useful when you look at a high scale map, as it helps to recognize
where you are, and where amenities are, to orient yourself (e.g. shops /
fast food, escalators, elevators, obstacles, etc.). With a linear way you
have these "levitating" around the way and don't know if they are
accessible or just nearby.

I think in the end we should have more than one stop position, if applying,
e.g one for "regular trains" one for "short trains" (in Berlin for
example), with tagging that says which is which.
