If it ever gets decided to do riverbanks as just polylines instead of complete polygons, the main effect will be that the processing will be pushed out-of-line just like the coastlines are now. We'll have to generate seperate riverbank shapefiles for all the riverbanks which with then have to be processed seperately in the stylesheet. We support the usage of polylines for coastlines because we pretty much have to. But PFTLOG don't do go suggesting polylines-for-areas for everything just because it would be nice, because it really just isn't nice at all... polylines-joined-by-a-relation is cool, no problems there.
