People use addr:street for Chinese in Taiwan

Yes, that's called Karlsruhe Schema[1], which can be used for partial
surveys or a building sharing many house numbers

Example can be found here - http://www.openstreetmap.org/way/183321090

Some osm render can draw interpolated house number.
In theory, that geocoder developer can use interpolation[2] to parse
the location. but I never see a geocoding service based on OSM using
interpolated address number.
