Test for landuse inside landuse

[naoliv]

I can't say the global number of landuses inside landuses with the same values, but, as an example, in Brazil we have right now 288 landuse=residential areas inside another landuse=residential area.

area[tag("landuse") = parent_tag("landuse")] ∈ area[landuse] {
        throwWarning: tr("{0} inside {1}", concat("landuse=", tag("landuse")), concat("landuse=", tag("landuse")));

Is it worth to include a similar test in JOSM?
