1. We don't do backports, so this definitely won't be fixed for this version.
2. We could add an API here so other mods could map a level data to the PrimaryLevelData (or more specifically, WorldOptions ) we need here. Then a compatibility mod or WorldGameRules itself could register the mapping. A PR for the API would be welcome, and should be added to the NeoForge side at the same time.
