People often mock gluten free labeling for products that should either be obviously gluten free or are not food. But the range of gluten sensitivity does vary, and there are people who react to gluten in cosmetics (where it can be added). There are also cases where gluten is added to food where it would not be expected.
If you are gluten free because you can't tolerate gluten, that labeling is very helpful.
