This is a datapack that changes the overworld generation to create islands in an endless ocean. Along with changing the biomes, the terrain has been slightly altered as well, always being flatter near coasts for the more traditional survival island experience, as well as making oceans ~1.5x deeper. It is a very small modification and should be compatible with most other biome and terrain mods.
I highly recommend using Jacobjo's Datapack Map to scout the seed if you are wanting to find the perfect spawn island.
