It's true that shop tags on building outlines are a common practice. However, POI nodes inside buildings are likewise common. So I believe it was a good idea for Joseph to remove this statement. It did present a widely accepted practice as a "bad situation" in need of fixing, after all. > It is fine to map multiple real objects with one osm element It'd say it's ok as a shortcut during initial mapping, but it is far from ideal. As soon as you want to add tags which only apply to one of the features (you mentioned "start_date" or "operator" as two examples, but of course there are more), using separate elements becomes necessary. > Nothing new, this problem already existed with roads and bridges and was > fixed by putting bridge name into bridge:name tag. It wasn't properly fixed until the introduction of man_made=bridge – that is, a separate OSM element for the bridge. The bridge:name tag was only a band-aid for a single symptom of a deeper issue. It did little to address the other symptoms, such as multiple roads running across the same bridge, and tags other than name.
