The base recipe for mass generated recipes like the color variations should be editable. SO in the base modpack the recipe should be declared. That way, with a datapack, a user can change the recipes from iron ingots to copper nuggets or wire if their modpack has it. Then on launch the mod regenerates the recipes using the new template.

I support it. I have this problem now.

you can use CraftTweaker or KubeJS to tweak recipes
