[Tagging] Wiki edits, building tags on nodes versus areas

[Andrew Hain]

Over the past few days there have been a number of wiki edits (mainly but 
not entirely in German) stating that shop=* and similar tags, contrary to 
the “One feature, one OSM element” principle [1], should only ever be put 
on nodes and not on building polygons. I’ve commented on an affected talk 
page without any response.

Is there any justification for these edits?
