You have forgotten at least one - landuse=farmland, crop=grass.
However while landuse=meadow and my addition may have grass, it may not
always have grass for instance after a harvest the grass may be gone,
but the land use remains. So these area could have both a landuse and a
landcover. I see nothing wrong with that as they are separate things.
A 'natural=grassland' ... has been misused .. so maybe better to use
landcover=grass and then some subtags to specify whatever is the
differences that people want to map. For instance the height of the
grass .. 2 meters in some parts of the world.
Solution(?): 4+ tags for areas of grass with overlapping meaning, in 3
different keys
I don’t see how this will be an improvement.
Even if you succeed in replacing over 5 million uses of landuse=grass
with landcover=grass there will still be areas of landuse=meadow and
natural=grassland which are not precisely defined, not to mention
other areas with grass surface such as leisure=pitch and
leisure=recreation_ground, landuse=village_green, landuse=greenfield, etc
landuse=meadow should delete the vegetation in the description leaving
the use ... "Used to tag an area of land used for hay (meadow) or for
grazing animals (pasture)." That would make it clear and possibly reduce
its misuse. If you can only see grass then you don't know if it is a
meadow, so don't map that .. but map the grass!

We have significantly updated the proposal. We have removed most
of the proposed values and only trees and grass are left. This to
reduce the scope of the proposal.
We also tried to better explain that with this proposal, we aim to
improve the tagging scheme in the long term. This proposal is
basically a building block other can build upon to improve the
tagging scheme (e.g
https://wiki.openstreetmap.org/wiki/Forest#Which_tag_should_be_used?).
I hope that this address some of the raised concerns and creates
more meaning for the proposal.
Kind regards,
Vincent
