Reverse Geocoding with OpenStreetMap should add house_number to street

OSM sends a house number as an extra field, e.g., which should be added to the street property of QGeoAddress.This would be correct with regards to the documentation:

This property holds the street of the address but may also contain things like a unit number, a building name, or anything else that might be used to distinguish one address from another.

and there is no other way to retrieve this information.
