(Compromise is currently done on rendering/data extraction side.
Nobody cares there about natural/landuse/landcover whatever. It's one
forest and that is it)
The only other way is to use de facto situation - natural=wood and
landuse=forest - and forget this discussion.
In terms of topology, the idea from some that 'landuse' only applies to
land that is 'used' for something implies that large areas of the planet
are 'unused'?
Or unmapped for human use.
Given that the tag landuse may not have a good value for what the mapper thinks
the area is used for,
or they think a different tag ... such as used for a National Park is all that
is needed to describe the land use so they leave the tag landuse off.
So I think rather than 'unused' they are 'unmapped' and/or the definition of
'use' has not included all the possible tags that could be interpreted to be
human use.
A single layer of areas defining the current 'landcover'
should be something that is managed even if that includes 'wood-managed'
and 'wood-unmanaged'. The current historic situation has never been
right but then so have other long-standing compromises in tagging.
P.S. And all I wanted was to talk about topology rules... BTW: here is
an example of topology rules in Lithuania:
https://wiki.openstreetmap.org/wiki/WikiProject_Lithuania/Topology_rules
In terms of the UK, Land Use and Land Cover is well defined with a set
of clear classifications
https://www.gov.uk/government/statistics/national-land-use-database-land-use-and-land-cover-classification
except they are not really THAT clear. In your rules #2 and #5 seem to
be at odds? and in the UK classifications, just how do you define the
wooded areas of a park ... which may or may not be 'managed' ... and are
combined with 'grassland' and other natural or managed landcover. We can
define landuse=park, but that park can have a lot of detail contained
within it ... We are looking to render blocks of trees, grass, and other
objects how ever created?
A botanic Garden contains lots of different plants, including grass for the
ones I have been to.
Mapping each individual plant with its species and genus ... no thanks.
I did map one tree though, just to be inconsistent. :)
