To me, "urban_green" is not a land use. I don't see "urban_green" as a 
good value. What use is it put to? Park, recreation, something else?
The use of "green" implies a land cover .. not a good thing in a land 
use key.

Mixed vegetation? Possibly better with separated values grass, trees, 
shrubs???

Any depreciation should include some suggestions for alternative tags - 
so people have an idea of what to use in place of the depreciated 
key/value. Possibly there might be more than one replacement.
