I tried your patch today, and I think it looks quite promising. Implementing such a strict scheme will certainly show some faulty multipolygon (e.g. Aussenalster in Hamburg), but perhaps this will encourage a cleaner tagging of such relations. I think the patch has still one problem: If the tags of the outerpolygon are not used for the multipolygon area, they must still be used as a stand-alone polygon. As an example take a nature reserve consisting of a wood with a lake inside. This migth be mapped with two polygons and a relation: polygon A: leisure=nature_reserve (the complete area) polygon B: natural=water (only the inner area) multipolygon relation: natural=wood and outer=polygon A and inner=polygon B (only the surrounding area) Right now polygon A seems to be missing in the resulting map.
