It seems that many people in this discussion take the value "grass" so 
something extreme. The fact grass is used, is because it is currently hides 
the surface in the rendering, and no other common value of unpaved areas 
exists that fits the bill. Personally I find highway=service, 
surface=grass, area=yes appropriate for the camping site but not when it 
rendered as paved road.
