According to tagstat, denotation is used ~2,600 times, which is less
than 1% of the 372,969 trees. So maybe Martin's statement that ~80%
didn't consider the wiki definition authoritative isn't true, but does
"~79% didn't consider the definition authoritative" really change the
situation?

I /do/ agree that additional tags such as denotation is a solution for
the problem, though. But imo, we shouldn't rely on tagging all ordinary
trees with a "nothing special about this tree" tag. Instead, we should
tag those trees that are something special - which also allows us to
indicate what's so special about that tree.

If a tree doesn't have additional tags, the obvious interpretation would
be that it's, well, just an ordinary tree.

It's not compatible with ~79% of the existing uses according to your own
estimate. It's not compatible with JOSM's presets either (they assume
that natural=tree means "tree", and mappers using them relied on this).
And it's certainly not compatible with the intention of unsuspecting
mappers who used natural=tree without looking up a definition - because
the meaning seemed completely obvious to them.

A failure to adapt the wiki definition to majority use by removing the
"lone or significant" limitation would start an eternal struggle against
the massive influx of trees tagged "incorrectly" by mappers relying on
their common sense.
