that's why I took the time to describe what a correct meaning
of landcover=artificial could be.

practical example : industrial wastelands that have a few square meters 
of concrete, a few square meters of asphalt, some metal plate...
I have no interest in making an object for every different surface but I 
may still want to to describe that this part of the landcover is 
artificial and that this part of the ground is of wild vegetation type.

Other concrete use: some municipalities charge a variable fee for water 
collection depending on whether the landcover is artificial or not. 
Calculate the artificialisation index is currently impossible given the 
absence of generic tags by category (not everyone necessarily wants to 
split a landuse=residential into a few square meter of "vegetable 
garden", a few square meter of flower, 10m2 of lawn, 5m2 of bush, 1m2 of 
clay, grass, a terrace (whose coverings are sometimes so "imitation" 
that you are very lucky to be mistaken in trying to inform the ultra 
precise type... e. g. concrete imitation wood)...

We do have highway=road and there is no majority opinion to request 
their removal because it is unclear until someone has been there to make 
a choice of a more precise value
