This data pack makes the Overworld consist entirely of caves. It doesn't use Nether generation, but rather the vanilla Overworld cave generation, just extended all the way up.
Please note that there is a bug where some seeds will spawn you on the Overworld's bedrock roof. I haven't been able to fix this, so if you spawn there, enter spectator mode or try a different seed.
