Xfce 4.10 released

I don't think that theory holds much water. Redhat is not the emperor of Gnome. It seems that Gnome project itself is rather independent tends to do what they think is the best.

Besides that if you don't like change, then don't change.

Redhat 6 is going to remain comfortably Gnome 2 and will continue to be a supported system all the way through 2020. So there is really no reason for a customer that wants avoid Gnome 3 to use Gnome 3 for a great long time.
