From reading this list, I'm aware the use of wheat starch is not recommended.
Old Windmill produces  "gluten free bread and baking mix" that contains
"gluten free wheat starch" and makes a loaf of bread that in looks and
texture resembles the real thing. They claim the gluten content is so low
it can not be measured.  Do many people use this product? An acquaintance
who has an extremely sensitive case of dermatitis herpetiformis has used
this and shown no reaction.
