17000 x landcover in the database, by 748 different users, of which 9300 are trees,
is definitely support. Probably the key should be refined and documented more precisely.

Which makes a lot of sense. I often have cases that a commercial or residential
plot of land (which boundaries are now mappable from open land registry data)
which is covered in parts by certain vegetation or surface (which is visible in
aerial photography).

Being able to combine these different sources will bring out the strengths of OSM.

The tag also helps to solve the issue that nature claims back land that is not
used by humans anymore, with arbitrary vegetation, and no land_use_ tag fits.
