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.
