the difference though is that in many countries every road has a roadsign identifying it as some kind of primary - secondary road type, also having legal implications someplaces. That doesn't seem common for rivers and I am wondering if this information will be ever useful to anyone.. probably not even your renderer as it would take years before a notable part of rivers are tagged. Some rivers have waterway relations which could be used to make some classification?
