I agree. Areas will come ever more complicated with data imports and
tracing from high resolution images. I checked that the biggest lake
polygon in the official Finnish mapping data has 287273 vertices, 5484
islands and the total length of this simple polygon is more that 5276
kilometers. It would be quite a beast as OSM multipolygon relation.
