Deep Warm Ocean

Did you know that deep warm ocean biomes don't generate naturally in Minecraft? This finally implements them so they can.

I wanted to build an undersea base deep below the surface with a big glass dome amidst a coral reef. Then I found out that while all four of the other-temperature oceans (lukewarm, ocean, cold, and frozen) had a "deep" variant, warm oceans - the only oceans with coral reefs - were unfairly left out; deep warm oceans do not generate. An unfinished version of them exists already in Minecraft's files, but it can only be seen in buffet-type worlds and it's missing the crucial coral reef part.

To find and visit a deep warm ocean quickly in your world, use this command in the overworld:

/locatebiome deepwarmocean:deep_warm_oceanfollowed by:/tp 0000 ~ 0000replacing the 0000's with the coordinates displayed in the chat by the previous command.

Admittedly, I have no idea what I'm doing: I just used MCreator to make a super-simple mod that injects a sparse "dummy" biome into Minecraft's Overworld and then snuck a single-file data pack into the .jar that changes that dummy biome into a deeper version of the naturally-spawning warm ocean biome, complete with coral reefs. All I can say is this mod works as expected when tested on a new world, including when others' biome-adding mods are loaded.

• This mod will be eventually uploaded and possibly maintained on Curseforge, but only after login options other than Twitch become available there. Until then, it will likely only be available on Planet Minecraft and at the Dropbox and Github links provided here.
• Feel free to upload this in a mod pack.
• I have no idea how to port it to Fabric or other versions, so you can do that too without asking - and honestly you don't even need to give me credit if you manage to port it; you'll have done more work than I did by that point.
