[Tagging] The endless debate about "landcover" as a top-level tag

If a country's community decided to adopt one tagging method of forests,
wood and tree areas, and retagged all existing usage accordingly, more
could be done with (answered by) the data for that country. As it stands, I
don't see that happening in any country any time soon.

Especially natural=wood and landuse=forest are used effectively for the
same purpose. landcover=trees is gaining as an additional tag in the
expectance of (or hope for) future rendering. A lot of landuse=forest gets
landcover=scrub, by the way. When/If landcover is rendered, a lot of small
areas tagged landuse=forest and natural=wood within all kinds of landuses
would become just smaller landcovers over bigger landuse areas.  Then you
would still have the two wood/forest tags with very much overlap in meaning
and exactly the same rendering.
