Define significant. Sesame allergies are pretty rare, but, where present, are extremely dangerous. Generally these mandated warnings are based on some combination of prevalence and severity; sesame allergy is rare but use of sesame is common and the allergy is lethal, so it gets a warning.
The one that confuses me is lupin. It’s one of the 14 mandated allergen/intolerance warnings in Europe, but is not at all commonly used.
It's commonly used as an alternate plant in soy fields, for crop cycling purposes. I forget which nutrient it prevents oversaturation of, but there is one.
Lupine fixes nitrogen from air, making it effective as fertilizer.
