I was with you until you mentioned over-reaching. Problem is, there's a small segment of the population that will literally die from sesame. 0.3% total sesame allergies, maybe less will get death as the side effect. It's perfectly reasonable to require companies to omit sesame from products that don't have it labeled, and forbid cross contamination. It's also reasonable for companies to consider including it and labeling it for ease of operations. I worked in the food industry and dealing food cross-contamination is really hard. There is no one-size-fits-all for public health on a scale as large as the US.
