That's good, but the thing that really frustrates me about Ubuntu is that they don't update to Gnome point releases (except for LTS versions of course). The Gnome X.0 releases in March and September, and the Ubuntu releases provide the Gnome X.0 release in April and October (typically). That's all fine.
But then Gnome releases X.1 typically 6 weeks or so after X.0, and X.2 6 weeks after that, and sometimes even X.3, and those are chock full of bug fixes and stability enhancements. But Ubuntu never updates to those in standard releases.
They may pull back a critical fix here or there, but that's it. And so it seems that Ubuntu always has the worst of each Gnome release: they get all the new features in release X.0 without the bug fixes that went into release X.n, then they jump to a new release X+1.0 with lots more new features without fixes for those bugs.
If they start picking up the intermediate Gnome point releases in this "rolling release" model, that would be completely excellent.
