a node is a good representation for a spot, but not for a clearly defined area. If the housenumber is valid for an area it should be better put on this area, and in theory you would only have to put housenumber tags on those objects inside this area, that have different values (if any, it's a very rare case) - in theory because in a project like osm it can help debugging and quality to have the address repeated on a poi (especially if these objects are mapped as nodes, whose position is often less obviously off than that of areas. Areas can usually/often be associated to features you see in aerial imagery, while this is less true for nodes). 

I'm not in favor of using different tags here (contact vs. addr), a housenumber is a housenumber, and it is never an object of its own (in the real world), it's always a property of something (a site, a house, an apartment, etc.), even if in osm this is less clear because most housenumbers are currently tagged on nodes with only addressing information, and because routing programs treat addresses often as POIs.
