what about a check, if left=~-180 or right=~180, if this is really the leftest|rightest part of the map, or if it continues on the other side on anti-meridian. If so, divide bounding-box at anti-meridian into two parts and calculate tiles for these two bounding-boxes.
Yes, I think the problem is if you cross 180. Maybe if the data is going from ~-180 to ~180, we should check what the latest node from the right is, and what the latest node from the left is, and exclude the empty middle?
I thought the same and coded that before, but the problem would be the same if you use a polygon containing e.g. all countries using french as the national language. I think it is not good enough to creae two distinct areas if the original polygon contained more than two, and guessing the original polygon is not trivial, esp. not if it contains small areas around islands.
