Yes. And therefore the problem lies in the rendering rules, not the
underlying data, that's why these should be modified, not the data.
Actually I can think of no case where water should not be rendered
above other nearby polygons. The only situations would be covered
underground water bodies, which should be tagged with a layer-tag and
probably some yet-to-come-underground-tag, so I think this issue can
be solved. (Probably the suggestion to map the water explicitly above
and tag it with natural water, tidal=yes is the best hack proposed
till now, but of course remains unsatisfactory).

IMHO it is important.
