I understand from other issues posted here that, if your modpack does not have a mod supported by Extra Bees, the bees meant to produce products from that mod become unavailable. Since Modtweaker allows us to edit centrifuge recipes from Forestry, I would suggest adding a config option to make all bees and their combs available regardless of what mods are in the pack. That way, modpack authors can add support for mods Extra Bees does not support by making centrifuge recipes for combs that would otherwise be useless. For example, since I do not have Buildcraft in my pack, I do not have access to Oily Bees, but I would like to use them to make oil from Immersive Petroleum.
