Hi!

so 2 trees are a "cluster"? IMHO that's also agains your own
intentions, because 2 trees can be as significant as one. Even three
or four. Traditionally, oaks appear in small groups of 3 to 5
("Eichengruppe"). They are mostly landmarks or at least good points
for orientation.
Why don't you simply tag the landmark trees as landmarks and keep the
trees being trees? WIll we have all trees that have at least another
tree within 50 metres as "cluster" in our database in the future, i.e.
thousands or even millions of them?
Because you only can assume that something probably is a landmark.
But it is a fact that a tree ist not standing alone. I'd rather mark facts
with a tag.
Maybe I'm missing something in this discussion, but what exactly is so
important about the fact that the tree is standing alone that it needs to
specifically be tagged as standing (or not standing) alone?
Many OSM features stand alone, but there has not in the past been a need to
make any special notice of this, or tag their proximity to the same features
nearby.

And it is a heuristic. Of course it is possible that there may be special
cases where it is not correct. But if you look at the massive heaps of
trees
they are whole citys mass imported from some data source without further
tagging, probably none of them are landmarks. So I am content if it is
only
99% correct.
If you want to oppose this approach, please show me a few 100 examples
where
it went awry. A debate only makes sense if the debate does not take more
time than fixing the exceptions. And it does not make sense at all if the
problems are only theoretical.
