[Tagging] Basic cartography features missing, why?

Probably the database should be organized in layers. The more 
information there is, the messier it becomes to have everything visible 
at once. With JOSM you can sort of simulate layers with filters on tags 
(I use that feature all the time), so I'm not sure if it actually needs 
to be layers in the database or if it just needs to be adaptation on the 
tools side.

I disagree that names in the landscape is of little value, and actually 
defining what it is covering is providing additional value over just 
placing a point, and I think is opposite to tag for the renderer.

And in the end it's about the resulting map. The current use of points 
won't do what's required to be able to make good cartography.
