[Tagging] trees and waterways

[Nathan Edgars II]

I'm wondering what the difference is between the recent discussions
about trees and waterways. Here's the way things look to me:
*The wiki says something should be tagged a certain way: ("lone or
significant tree" for natural=tree | "direction of the way should be
downstream" for waterway=river, stream, and maybe other values)
*People don't always see the definition on the wiki, and thus don't
tag according to it, instead: (using natural=tree for any tree | not
determining which way a waterway flows and drawing it in that
direction)
*Many features are now mapped differently from how the wiki says
Yet the result is different: with trees, consensus seems to be to
change the definition, while with waterways, we seem to be avoiding
the problem.
