12561	Warn before uploading huge features (especially buildings)	anonymous	team	"JOSM should warn before uploading huge buildings.

See for example changeset http://www.openstreetmap.org/browse/changeset/37377131 and german forum discussion at http://forum.openstreetmap.org/viewtopic.php?pid=579055#p579055 .

There is a warning for very large segments, but this should be clarified when the feature is an area feature or especially a building."	enhancement	closed	normal	16.04	Core validator	latest	fixed	buildings, size
