I am non-celiac, and am actually allergic to wheat. I am allergic to a different part of the wheat than gluten, but the gluten free stuff is inherently wheat-free so I'm all over it.
Since I don't get ragingly sick like a celiac would, I don't care about using the same tins and bins as had wheat, etc. in them. As long as they are washed, I say they are fine. I also don't care about the products that say "produced in a facility that also produces wheat" or "may contain traces of wheat" like a celiac would.
If you're not celiac, I would say fussing over it is more stress than it's worth.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
