Ah yes, I can see this. I've also seen this kind of 'universally understandable spec of behaviour' attempted from the other direction with things like plain-language cucumber test definitions. Emphasis on attempted, not sure I've ever seen it actually work as envisioned. Can see how bringing this directly into the code could remove some hurdles though. Must say though I am a little skeptical on the readability / comprehensibility of the JSON format as you point out, but it's certainly a cool idea.
