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
