Overview

For example, completely remove the heating of wool armor heating or make a super cold ice biome.

Maybe there is such a function, but I did not find it. I will be glad if they add it or tell me where it is, if it is available.

Why would this feature be useful?

It will be useful in some maps or modpacks.

This is already possible with datapacks. You can find an example datapack in the pinned messages of the Tough As Nails channel on our Discord server: https://discord.gg/GyyzU6T
