I don't want to push the issue - and there is little chance for such a 
suggestion without significant parts of the local community feeling a 
need for this on their own.

Since I am pretty sure quite a few of the mappers from Sweden and 
Finland read this list people are likely aware of the problem now 
(likely were before in some way as well).

Despite this the whole matter also has a more global component of 
course.  Mapping of the large wooded areas of the planet is a problem 
in OSM that is going to bother us for the forseeable future.  Right now 
the only areas where you can produce larger area maps with forest 
rendering in good quality based on OSM data alone are western and 
central Europe (mostly, there are gaps even in that, in particular in 
the Italian Alps).  And these are obviously not particularly difficult 
in terms of forest mapping.
