There's 'Duplicate edge' which is easily resolved by e.g. separating a street from the edge of a square and then there are 'duplicate edge' where a e.g. complex pedestrian area is drawn, one part tagged with a cobblestone pattern, another part tagged as marble covered etc. Another simpler example a pedestrian area, bout 4 meters wide, 150 long joins a square https://www.openstreetmap.org/way/702458985 . The joining edge is marked as duplicate. It makes no sense to me why 2 in effect basically identical areas cant be sharing edges/nodes. Bar artificially separating them then create a single connect node 'to map around', no solution (and the facepalms are up to be slapped). Ref: wiki https://wiki.openstreetmap.org/wiki/Key:area:highway BTW, see these areas also often being thrown out as "no feature tag ways". Any ideas to resolve these with a note that 'not mapping them details is not an option'. OsmAnd e.g. maps some of these properly like the area:highway=motorway areas. cheers
