(setting aside whether it’s good to reduce demand for shrimp)
If someone is setting up this kind of precommitment I think it would be important to tie it to factors that would influence the success in the market. I would guess those are primarily cost and taste. Cost is hard to predict, and many things get far cheaper when scaled up, but taste seems pretty tractable. Perhaps tie the commitment to having a group of shrimp paste consumers ranking the substitute equal or better in a blind comparison (probably in cooked dishes, ideally where the cooks were also blinded to the condition)?
