I beg to differ, UGR should follow the Gnome releases and so should Ubuntu to benefit from the upstream Gnome releases.
The packages with the never Gnome would be just as well tested as with the older one as it has the same audience.
I don't think there is any stability issues with Gnome, but because Ubuntu chooses to have it's own versions of the 'System Settings' , onlinie accounts (UOA vs. GOA), compositing window manager (Compiz) and it's own Shell (Unity) etc.
There will be a process of patching and tweaking the involved Gnome components to meet Ubuntu's needs.
This process, I think, is what you all refer to as 'stabilizing' and 'polishing'.
It's an adaption process where Ubuntu has to adapt to the Gnome components because Ubuntu has not produced a complete DE yet and still relies heavily on Gnome to have a complete DE.
It has
nothing to do with the quality of the current Gnome version, and I really can't see that UGR would gain any stability at all from such a decision, but it'll gain less users as it looses it's appeal to Gnome fans because of an old Gnome version.
ATM there is no guarantee that Gnome 3.8 will make it into the Gnome3 ppa, because of incompatibility with Unity.
