The lack of nested rules shouldn't be a reason to introduce more at-rules. Shouldn't selectors and @rules be kept orthogonal?

BTW, I'm wondering why the spec is using a pseudo element instead of a new combinator like ".."? This has two drawbacks: firstly, consecutives pseudo-elements could become syntactically valid and "a::distributed(div)::before" does not make sense; secondly all the other pseudo-elements only match one element, not many. Plus, that's longer to type.
