Well, @supports certainly should, I think: the whole point of @supports 
is to test what's supported in the document being styled.

Whether the DOM API should match that is an interesting question.  I 
think it should, for consistency.

That doesn't preclude having this hang off a Window or window.CSS; in 
either case the current document is easily accessible.
