New ocean seed option

I think it would be cool to have an entirely ocean seed where all biomes are in the form of islands. They can be large islands, but not large enough to be called mainland, I just feel like this will make for some interesting worlds. This could be expanded upon with sky island seeds, entirely underground seeds, or a nether and overworld combined seed where nether portals don't work. Some of these are a stretch, but it's an idea, and it's an idea I'm personally find of. One of the worst problems about Minecraft is that terrain is 9 times out of 10, not that amazing-looking, and I think this, along with general improvement, could definitely benefit it.
