    interesting, can you give a real world example where a group of
    trees has actually the name “... forest”? I always thought a
    forest would require more trees.

Either one of us is completely misunderstanding what the other wrote or you're quibbling about the size of a group.

Sherwood Forest is 450 acres of trees.  It is a nature reserve and so it is not used for forestry (aka logging). There may be occasional felling of diseased trees but it is not systematically logged on a wide scale.

This is why landuse=forest is problematical.  Sherwood Forest is not land used for forestry, but it is called Sherwood Forest so landuse=forest may seem like the correct tag to use (because it says "forest").

That's why abandoning landuse=forest in favour of landcover=trees or landuse=forestry (as appropriate) is a good idea.  I'll also add that I don't think landcover=trees should be used in combination with landuse=forestry because what is currently on land used for forestry may not be trees but saplings or stumps.

I am coming around to this way of tagging.
Been looking at places tagged landuse=forest around me...
Some are forestry (yea!)
Some are parks ..
Some are nature reserves... (some of these are errors due to LPI map colours ... very similar from forestry to reserve. And yes, LPI is legally allowed in OSM) Some are no more trees ... history .. though I have found one that is forestry .. just with the trees harvested and gone, they'll be back.
