Currently in 1.16.3 there is only the command that puts all the biomes in the datapack folder, which has it's uses, but can we please have a way to print all of the biome names into the log as a straight text file so that we can add them to other mods for compatibility?

Crafttweaker did that with a command and it would print all of the biomes in the forge registry. Is there a way to do that in 1.16.3?

I'm gonna say no as this seems to be more of an issue unique to you and specific others but not everyone else. This doesn't mean I won't add it in the future.
