9651	Validade landuse=* on nodes	naoliv	team	"landuse should be used to describe the usage of an area.
Its wiki (http://wiki.openstreetmap.org/wiki/Key:landuse) also says that it should be used only in areas.
I see a lot of people wrongly using a single node with landuse=residential, for example (one example using South America: http://overpass-turbo.eu/s/2ku)

Could JOSM give a warning about using landuse on nodes?

{{{
#!rule
/* needs a better phrase :-) */
node[landuse] {
        throwWarning: tr(""{0} should be used only in areas"", ""{0.key}"");
}
