You’re the only one talking about niche/specialty products though. Not denying that those products require extensive research, but I doubt that those products alone are responsible for the considerable markup on the typical alternative milk products, which truly are closer to “oats blended in water”, and probably make up a majority of sales.
I think there is a huge difference in the thing you are describing and e.g the oatly barista.
There are a lot of oat milks that taste very different or not at all. To get the right taste and consistency, you need some research.
