What is a 'real forest'? Compared to this 'residential area with large gardens
and trees'?
Would not the area give away what you would find there?
How is a small area of trees different from a larger one?
This is exactly why I started the topology rules topic. What we're
doing in Lithuania is we have to separate types: general forest, and
forest inside residential, commercial, industrial zones. The later one
is usually just a small number of trees in an area which is marked as
say residential zone in official maps. The later one can easily be
skipped in a map and result would not have "holes".
So even if we're using two tags in Lithuania, I'm fine with choosing
one tag for all forests/woods/trees/whatever and then if someone
needs/wants - they could add subtags for details.
Introducing even new tags seems impossible (and impractical) because
absolute majority of mappers just want to tag "forest/wood". And they
don't care about the details, so they will not tag it. And I do not
know maps which would somehow use such data, especially when such
detailed data would only be filled by a few, so it will not be filled
in a large enough regions to do any reasonable analysis.
In that case used 'natural=wood' and be done, no sub tags.
That has no implication of 'managed' and according to parts of the
OSMwiki includes 'unnatural' too.
