From 2010 to 2012 the mapping of waterway relations has been unified
and https://wiki.openstreetmap.org/wiki/Relation:waterway was the
result of it.

Part of the discussion about the tributary role is here:
https://wiki.openstreetmap.org/wiki/Talk:Relations/Proposed/Waterway#tributary_vs._tributary_of_relation_role

The role has not made it into the the final definition of the waterway
relation model, but is still used in France.

You can see the bad side effect in Wikipedia:
Nice rivers in the map:
https://en.wikipedia.org/wiki/Danube
https://en.wikipedia.org/wiki/Mississippi_River

The Seine with it's tributaries
https://en.wikipedia.org/wiki/Seine
displays the watershed.

In parallel there is the
https://wiki.openstreetmap.org/wiki/Relation:watershed mapping. This at
least divides the mapping of watersheds and waterway into seperate
models. Nobody ever wrote a proposal about this.
