Pushing a new generator is mainly useful so things like progression-dependant item drops (e.g. guidebook) don’t affect levelgen otherwise. I can’t really do things like keep adding generator pushes for new content I add, it would become a mess, not work in all contexts, and the levels would still be different unless I did something like put in an option to just not include the new content. Every update since I’ve added seeds has done something that changes the dungeon and that’s just the nature of the seed system in a game that gets updates.
