I don't see a reason not to, since everyone agreed on it spec-wise.

Has the CSS WG explicitly cleared this to ship?

No, I don't think explicitly no. Happy to wait or whatever you think it's needed for that.

So I think we need to:

 1. actually write a spec for it; I volunteered to do that at TPAC but haven't gotten to it yet.  If you'd like to take a shot at it I'm happy to provide some guidance.

 2. Then suggest to the WG that we'd like to ship.  It might actually be possible to take the spec to CR pretty quickly -- but if the group wants to put more things in conditional-4, then maybe the answer is to clear the one feature for shipping.

I can try to give writing a spec a shot, but no promises at least just yet :)

What is currently blocking this from moving forward?

Comment 8

[Emilio Cobos Álvarez (:emilio)]

nothing, afaict. Spec-wise, merging conditional-4 / conditional-3. Will send an intent in a bit.
