Re: [csswg-drafts] Feature detection for descriptors

Yeah, it's Conditional - this is precisely why we took care to include arbitrary functional terms in the @supports grammar which resolve to unknown, so we can add more types of support-testing in the future.

(Need to also be able to test for types, like if "1foo" is a `<length>`, etc.)
