Is it ready? It was added on 4th June, but that was actually a bit premature it turns out, because upstream publish releases but say they're not for wider distribution for a while. Anyway, it was declared ready for general use on 10th July, which makes that 30 days, even though it had a lot more testing in Gentoo anyway.
OK, let's go ahead then.
