I would avoid retagging railway:station_category as
railway:station_category:de because there is no need to retag all
stations and halts and because there is no conflict to other tags.

I agree this system but I suggest to introduce two additional levels.
Not only train stations are tagged with railway=station. This tag is
also used for subway stations (often together with station=subway).
Almost a year ago I have been asked by Mentz DV if there is a
differentiation between minor and major tram stops. There is no one at
the moment (you have to count the route relations whose member the
stations is). That's why I suggest to extend this tag to every
station/halt where a railway-like vehicle stops.

*railway:station_importance=minor_urban*: The station is not served by
trains (i.e. only by subways, light rails and/or trams). Stations of
this importance are only few hundreds of metres apart from each other.
There is no change to other subway/light_rail/tram lines possible there.
Change to bus lines may be possible there.
Examples: Plieninger Straße in Stuttgart [5], August-Bebel-Straße in
Kalrsruhe [6]

[6] http://www.openstreetmap.org/#map=17/49.02436/8.37735&layers=T


*railway:station_importance=major_urban*: The station has importance for
a subway, light rail or tram transport system. The station is only few
hundreds of metres apart from the next station of this category or the
category minor_urban. There is change to other subway/light_rail/tram
lines and (optional) to buses and trains possible there.
Examples: Möhringen Bahnhof in Stuttgart [7], Neumarkt in Cologne [8]

*Other Examples*
Stuttgart Nord, aka Stuttgart Nordbahnhof would be "regional" because
the S-Bahn to Weil der Stadt, Bietigheim-Bissingen and Backnang stops
there. http://www.openstreetmap.org/#map=18/48.80352/9.19036&layers=T

Berlin Warschauer Straße would also be "regional" because Berlin S-Bahn
runs far out of Berlin (e.g. Strausberg Nord).
