I notice that this mod has a potential api for easily adding custom loot categories, would you like make it an independent mod? Like using datapck or config to customize new apothic loot categories then with (datapack) customized affixes we can create new unique weapon genre.

I don't think Apothic Compats invented any specific API for loot category creation, it's just adopted the experimental EntitySlotGroup API that was brought up in Apothic Attributes 2.8.0 + Apotheosis 8.3.0
