The mod "Creeper Overhaul" adds several new creepers, most of which are basically just reskinned creepers. In combination with your mod (Creeper AI Updated) though, their AI unfortunately does not change. I am suggesting a whitelist function in the config to decide which mobs get the same updated creeper AI because I think this is the most flexible method while also adding compatibility to other mods, and allows modpack makers to pick and choose if they want to make other mod's creepers different. Also, a couple of the creepers from Creeper Overhaul actually don't explode and instead do melee damage, so this method could work well in situations like that.
