Spontaneous Explosions

So I'm looking at the 'new' partial re-adding of customized worlds.

It's not as good as it was before yet.

But the format of the exported json settings from a world are in a format very similar to Bedrocks custom biome json format. So that's interesting.

Maybe custom biomes will be coming to Java data packs soon? Idk. 

But this new custom worlds thing does technically allow for new dimensions, but idk how you access them.
