There is difference between these types of water flows. You can read about
it in this article
So in fact you are putting categories into names just because they do not
match the OSM's tags.
In Russian for example we do not put "River" into river names at all
whereas in English you do it always.
Another example is that in English you always say "Lake Baikal" whereas in
Russian it is just "Байкал" (without the "lake" word).
In Russian we have very strict difference between a proper name and a
common name. Whatever characterizes a group of objects is called common
name, e.g. "street", "school", "hotel", "river", "stream", "creek" etc.
Alsmost any proper name can be used without it's common name depending on
the context, e.g. if you are discussing "Atlantic ocean" with your friend
you can say just "Atlantic".
So this topic was raised as a suggestion to distinguish between proper and
common names strictly to put only proper names into "name" field and common
names into some other field taking into account that language specific
common names very often differ from the generic categories adopted in OSM.
Without that distinction OSM cannot be called a true geospacial database
because there are no fields which let you query data by it's real category
(common name), you currently have to do that by analysing the "name" filed.
I understand that this would be a very big change but on the other hand it
would open doors to utilizing OSM for absolutely any purpose, not just for
