Regarding the upgradeable commas.
Let's say a property has grammar `<length>#{2,}`. Then `mix(50%, 1px, 2px, 3px, 4px)` is not ambiguous (1st value must be `1px, 2px`, and 2nd value `3px, 4px`).
But later on we relax the grammar to allow `<length>#`. Then `mix(50%, 1px, 2px, 3px, 4px)` suddenly becomes ambiguous!
So even if not ambiguous, I would prefer to forbid values from having a top-level comma when the author uses `,` instead of `;`. With the exception of `var()` to avoid breaking things.
