While you may find it annoying, the upside of this is awareness. More people are aware of gluten intolerance than ever before, and for people with celiac's and serious gluten intolerance, life is now much easier.
I've come across accounts of celiacs who are concerned that the rise of gluten-free options while expanding their menu options, has also raised their level of anxiety. Because some places might just be trying to adapt to a fad diet, but aren't taking enough precautions to avoid food cross-contamination, such as re-utilizing utensils to cook "gluten free" foods.
I think part of the concern is that "gluten intolerance" as a serious medical condition is getting overshadowed by the flaky diet mumbo jumbo.
