I don't expect anyone to do this. I just noticed that we lack any
worldwide classification of waterways (other than stream/river), which
could be valuable data for different things. Some things can be computed
and aggregated, but others are tagged as a general property - most
notably highway types.

This list is about creating standards for tagging. I ask here how to tag
existing river classifications if someone wants to use it, not insist
that we have to do it.
