They reworked perks such as sabotuer to prevent it from countering specific killers. Using that same logic, I don’t think they’ll add perks which counter a very niche and weak perk. Also, if you were to bring a perk that counters franklin’s, you’d most likely be doing it to make sure you keep your item because you’re worried about losing it completely. This would not help in that case, either, as you’d lose the item even if you escaped with it.
