@ fkv: The inconsistency you are describing is wanted, isn't it? As I understand it, pedestrianised roads should always be mapped as ways and only squares/plazas should be mapped as areas (see https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpedestrian). Graben and Kärtner Straße are pedestrianised roads, Stephansplatz and Stock-im-Eisen-Platz are plazas.
