Well of course, providing a solution for people with Wheat gluten sensitivity was not the original intent. However, if carrying the label “Kosher For Passover” assures a person that they can safely enjoy a food, than more power to you! It is an unintended but good result of the Biblical Command not to have any leaven or similar products in the home during Passover.
But, once again, The motivation behind Campbells’ action was not to make a better, healthier product, but to APPEASE a segment of the population that will not be happy until they have destroyed our civilization and our culture. And that I will NOT subscribe to...
The backbone of the story is the plight of the hapless mother as she attempts to find husbands for her daughters going so far as to let Lot take her and the kids to a city (at least a town of some kind).
Things go bad, and as predicted for thousands of years before, a mother who fails to find husbands for her daughters will turn to stone and the daughters will have to sleep with her husband to have children.
Now that take on the story might not be one you've heard before, but those items are in there FUR SHUR. The fellows inspired to bring forward the ancient stories provide substantial commentary to explain motives, but the "unleavened bread" demonstrates that we are talking about something made of grass ~ probably of the sort eaten by the wandering herds in the ice age. Not everything can be leavened successfully.
It's quite likely that in the most ancient times wheat gluten sensitivity was far more widespread than it is today.
