Actually, I wouldn't call that "ridiculous," I'd call it "accurate." Notice how landuse=residential doesn't overlap other, not-residential uses. Even leaves it open for potential landuse=highway area. Having landuse=* polygons overlapping entire regions is *much* more difficult to work with, especially when the edge extends close to or shares nodes with an adjacent highway centerline. Then trying to make an edit becomes a tangled, unwieldy mess in JOSM and just plain Not For the Uninitiated™ in Potlatch.
