Even the opponent(s) of changing the wiki's tree definition didn't try
to argue that the wiki definition was better than the alternative. There
was disagreement over whether c

oneway=yes has nothing to do with river flow, oneway indicate a legal

If we really need a tag to indicate river flow, it can't be oneway.
And if we define a tag for flow, how would you define the direction,

you'd want it to work with respect to the direction of the way, as

With the current standard, how do you add a source tag for the
direction? source:direction=I dropped dye into the canal and watched
it dissipate would conflict with a direction=* tag.

What properties of a way do you look at to determine whether it was mapped in
the proper direction? Do you have to check whether the node IDs increase in
the desired direction, or is there an easier way? Also, if it turns out that

But, in my experience, we do put oneway=yes on every motorway.

Tagging oneway=yes on a motorway is an example of tagging a special case. The
general assumption on roads is that they are two-way unless tagged otherwise.
Tagging the motorway as oneway=yes makes sure that routing calculations will
work correctly. Sections of motorways sometimes become two-w

And river implies boat=yes...
Those are special cases not the standard assumption for highway=* or
waterway=*
Idon't really understand where we are going in this

One type of map that would benefit from showing the direction of waterway flow
would be one intended for use with canoes, rowboats, or other muscle-powered
small boats. Paddling in the same direction as a river's current is much less
effort than paddling against the current.

The description there looks horribly confusing to me. The words
"homeless shelter" leap off the page, even though that's not what it's
describing.
