And what about =city_block , and =plot ? How can the larger ones as =quarter be indicated as a housing estate, with something else that’s different from place=estate ? What you suggest means place=estate counterintuitively doesn’t handle all housing estates. That’s misleading and a fragmented solution. Housing estate, gated community, whatever else is a concept orthogonal to the place= hierarchy. Mixing them isn’t a good solution from start.
What I may have said elsewhere, shop=mall and man_made=works are used for malls and factories besides landuse= =retail and =industrial , not some place= as awkward as =farm . I don’t see why should place= be expanded to more things covering different aspects.
