Actually the situation is even worse - current practice in tagging water areas is a wild mix of applying waterway=riverbank and/or natural=water to multipolygons, member ways and individual ways not part of a multipolygon. I doubt this is going to change as long as the common map render style simply renders everything with either of these tags in plain blue. Cases like the linked one are situations where even this basic handling fails (mostly due to broken multipolygons or inner rings tagged waterway=riverbank) And that's only for the water areas - i will refrain from getting into the water line features here. My conclusion on this matter is that the only thing you can currently do with the OSM water data is to render it - or in other words: treat it as mere information 'here is water'. And even that can be unreliable since intermittent=yes/water=intermittent are not consistently applied (not astonishing considering they are not rendered either). All information beyond that can - if at all - only be relied on locally if consistency has been maintained by local mappers or if most of the data is based on a well structured import.
