You are arguing that the regulation should be more complex... Regulations that require the allergen labeling and don't make exceptions will obviously be shorter than regulations that make exceptions. If the outcome were worse for consumers, I can see arguing for the more complicated regulation, but having a clear statement of the allergens regardless of the product doesn't hurt consumers any (If you disregard the bother from the redundancy anyway).
