Or should we create a new tag a tag like railway:station_importance=* with some category values such as local/regional/international/... and leave the existing railway:station_category=* tag for mapping country-specific categories?
I vote in favour for this idea to avoid a German viewpoint, and would like to rename railway:station_category to railway:station_category:de for this case. railway:station_category and railway:station_importance can thus be used in parallel. For railway:station_importance, I propose something like the following explanations (but I can only give examples for Germany, sorry):
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.
*railway:station_importance=local*: The station has importance for a few surrounding villages and/or towns. Some regional trains may not even stop here. (In Germany, this would typically correspond to Bahnhofskategorie 7-5, examples: rural stops, suburbs, S-Bahn stations)
*railway:station_importance=regional*: A stop with higher importance, for example a connecting station on a railway junction. At least all regional trains stop here, maybe even some interregional trains. (typically Bahnhofskategorie 5-3, for example Kreiensen [0], Rothenburg [1], or Großheringen [2])
*railway:station_importance=interregional*: The station serves more than only regional trains, it is commonly used to change for interregional and intercity connections. The station is usually the most important one of several railway stops in a city. (Bahnhofskategorie 3-2, for example Göttingen [3], Ulm Hbf [4])
*railway:station_importance=international*: The station is a big hub in the national railway system and serves long-distance connections to major national or even international cities. It usually also provides access to an international airport. (Bahnhofskategorie 2-1, examples: Frankfurt Hbf, Frankfurt Flughafen, Berlin Hbf, München Hbf, Hannover Hbf)
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]

*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). http://www.openstreetmap.org/#map=17/52.50642/13.45119&layers=T
