> but it is more or less worthless for farmers as anything other than a novelty

This is clearly not true, considering it has already been successful as a niche specialty product. So you're obviously wrong.

You could become right by weakening your claim. The wheat will remain a niche specialty product, and will not overtake other wheats in the mass market.

Specialty products made on a smaller scale can be plenty valuable and successful. They are not "novelty" products.
