This is another one of those discussion which comes up every year or so.
The perception of danger is subjective; which never fits well within OSM.
Waterways are not dangerous in themselves. They are inanimate objects.
They don't jump out & attack you as you walk by. It's the naive way
people interact with them which causes injury.
If there's a sign indicating danger, tag that.
