The fact that Canonical has always been happy to ship software that they know fully well shouldn't be shipped doesn't fill me with hope that it will even work decently without causing massive issues to everyone (remember when they started to use pulseaudio? In the end it was such a mess that the solution was to abandon it).
It was rough for a while, but my debian machine still runs pulseaudio and it works pretty well. I agree that ubuntu doesn't do enough testing before releasing stuff, but I am grateful that so many people are willing to grind themselves against the bugs before they hit more conservative distributions
