Oh come on. Did you think anybody would write an RFC in the comments? Add arbitrary list of whitespace tokens everywhere and pick whatever favorite grammar you have for literals. Json strings and numbers since you seem to like them.

Of course not. But you are at least semi-seriously trying to propose something. I promise you it won't be that easy to get any sort of agreement.

This is a classic "oh come on how hard can it be" that, once you get into it, it turns out the answer is very. Arbitrarily so. Agreement is hard. Details are hard. A standard with no details is not terribly different from "just give us some text".
