Dimension Seeds

Hi, with the JSON files for the dimensions, I've become aware that the seeds dont change as they're already preset, looking through vanilla code the seeds are set to 0 (which i assume is to make the dim seeds the same as the world seed) but it's still not randomising the seeds with the world seed, it continues to be the same terrain gen between worlds
