It would be nice if ReWIREDs heating/cooling cybernetics would activate when SimpleDifficulty is installed and interact with your mod.

That's actually from Cyberware/Robotic Parts itself, it's one of the few mods it supports directly

Didn't know that, thanks for the information.

I forgot to ask, when you say that it's one of the few mods that SimpleDifficulty supports directly, are you saying that anything that uses TAN is supported by default?
