I know this is really far fetched, and would require some really big changes to how a lot of things work, but it would be a cool addition if this ever managed to make it into the modpack. I totally understand if this is way out of scope though; there's a reason that nobody has ever made a split screen mod for java, ever.

iirc l4j is compatible with nucleus co-op, allowing for splitscreen
