In theory, I like trying to go towards "one feature in the world == one feature in OSM" but of course we break that theory a lot by splitting roads for various reasons. But being able to do a search for "Danube River" and getting back a single object from nominatim would be nice.
As pointed out, it isn't really feasible for some large objects. This could maybe be handled similarly to how route relations are done for US interstates and national highways. Each state has its own relation and then they are all grouped into a single master relation. this reduces edit conflicts and allows you to work with smaller chunks of the whole thing at a time. Nested relations can be a pain too though. So... it's complicated :) Even though I have done the Kansas River (which isn't *that* big) as a single MP relation, I wouldn't go changing what others have done locally with large bodies of water.
