Assign house numbers to squares, too

In Germany house numbers can be assigned to a square, but they aren't found by Nominatim yet. Three examples * [Rathausplatz 23, Lüdenscheid ](https://nominatim.openstreetmap.org/ui/search.html?q=Rathausplatz+23%2C+L%C3%BCdenscheid) That's the office of https://mvg-aktuell.de/ (address in footer) Nominatim returns the square https://www.openstreetmap.org/way/30425783 The expected address node is https://www.openstreetmap.org/node/6448615423 * [Gerhart-Hauptmann-Platz 48, Hamburg](https://nominatim.openstreetmap.org/ui/search.html?q=Gerhart-Hauptmann-Platz+50%2C+Hamburg) There's a restaurant at that address https://www.trattoria-vitello.de/ Nominatim returns the square https://www.openstreetmap.org/way/1185675089 The expected address node is https://www.openstreetmap.org/node/982084048 * [Markt 4, Vreden](https://nominatim.openstreetmap.org/ui/search.html?q=Markt+4%2C+Vreden) Dentist office https://www.zahnarzt-kemper.net/kontaktformular.html Nominatim returns the square, a node this time https://www.openstreetmap.org/node/8538665611 The expected address node is https://www.openstreetmap.org/node/8538185741 ## Further details I found the examples on https://nominatim.org/qa/#map=6.06/47.70/15.79&layer=addr_street_wrong_name There's some tiny squares, too. I've even found a city that put a 10m square next to a town-hall only to be able to have their address be the square (in honor of the previous mayor) instead of the usual street.
