No, they don't, and that's the point. It's just a big time waster from our point of view.
Acid test 0 needs it, and that's what put us on the trail, remember, but I think that's rare.
(At some point we might return to the acid tests as well, we can do both, real world sites and acid tests, but you see how acid could lead us astray, exercising things that just aren't used, or not very often.)

However, I found a way to improve it mightily, still with all the css functionality intact, and down from 1m10 to 20 seconds.
I think it's kinda clever, see the last push.
It will be hard to optimize this area further, without mucking seriously  with the third party software,
which I don't want to do, so we can just snap in the next version, with bug fixes enhancements etc, when it comes.
