Depends on what the name is seen as being.

Rendering questions elsewhere :) However ...

To me the rendering question is firstly - chose to render what as a solid colour - land cover or land use.

The the other one can be rendered another way.

But choosing individual mixed land covers and land uses to the rendered as solid covers just leads to confusion.

Unfortunately many others disagree here ... :)
The main OSM map renders grass, trees as solid colours, and residential areas too .. that is not good to me.
