When I think of why outlines don't make sense in this case it's because they further alter the coastline- that's all. We do all sorts of weird configuration to create certain visual effects. Drawing oceans to highlight land is an example in its own right. ;-)
Do outlines fix things at all zoom levels? What about the possibility of fixing the data? I mean, unioning the ocean polys into one, or better yet deriving land polygons from that data.

The artifact is getting worse in lower zoom levels (smaller islands). I just tried a huge overlap of the polygons which made it better but did not make it disapear also. So the workaround could be to find the perfect combination of outlinewidth (as small as possible) and overlap factor (also as small as possible). > Should an outline always be drawn? Tiled ocean polygons like I have them should be the perfect example where an outline just does not make sense. One would probably want to have an outline on the coastline but not on polygon borders. Something one would need to render from a separate linestring layer anyway.
