> @rniwa what if these "forwarded" selectors cannot include `:state()`? And what if they're only compound selectors? Wouldn't those two things make it easier to implement?

I don't see how. The fundamental problem is states like `:hover` implicitly affecting random other elements. That would quickly lead to O(n^2) behavior given the inherited value, etc...
