I think a lot of the gluten sensitivity comes from the ultra processing and degrading a food into the sum of its parts and than using those parts to make others foods or added to other foods to make them "better" in some sort of way . This fractioning is at the base of the ultra-processing of food, but wheat flour (normal white) + wheat bran isn't wholemeal flout, because you will have all the bad from the white flour and the gut irritating properties of the wheat bran when on its own.
Gluten has been added to so many products and in the long term, many don't feel great when having it. At the same time, whenever gluten is listed as an ingredient on its own and not the natural part of wheat, you will also have more ingredients and chemicals and additives. So it is the combination of these that exacerbates symptoms.
Real authentic bread isn't soft and spongy. If I throw a bread from a village bakery in France at your head, I will hurt you. The breads at the supermarkets? I can teach volleyball to my kids without fearing them hurting their wrists. Bread never was this spongy stuff.
Unless coeliac, going for a gluten-free flour is not a great idea, because, it is an ultra-processed high intervention substance, a great invention for the coeliac who have some alternatives.
For someone who has sensitivity and wants to try alternatives and more authentic breads, doing your own, is easy and way cheaper that those boutique bakery that sell real bread. Buy good quality flour and experiment in the kitchen.
Once you have mastered the breads you can become creative and do some biscuits, and cakes.
