The logic already exists in one place: osm2pgsql. One way to do it would be to use osm2pgsql to push it into shapefiles, from there they can be easily tiled. Now, I won't say the logic in osm2pgsql is foolproof right now. I do wish people/editors would add an area=yes tag to the non-obvious cases. Just because the API doesn't understand the concept, there's no reason why editors like JOSM and potlatch can't make the distinction.
