This would help to map areas of trees and grass comprised within a larger
landuse e.g. military, residential, industrial.
It would avoid the practice of mapping natural=wood or natural=grassland
for those areas.

How would you suggest we tag the middle of a roundabout with grass growing

natural=grass, can be combined with any landuse.

maybe, IMHO who adds natural=grassland to some square meters of grass in a

It's one of those things mappers do because it's close enough, which you
abandon the moment a better solution is available. Mappers also tag tiny
patches as "forests".

It accepts the current practice that the natural key describes land forms

natural= is no longer reserved for naturally occurring feautures; de facto
it means that the feauture forms, flows or grows by itself, whether or not
it is planted, planned, guided, intitiated, shaped or groomed by humans.

Over here we have trees in oversized flower pots decorating some roads -
they still are naturals, because the trees grow by themselves (and even
though they are replaced when they grow too large for the pot).
