The problem is configuration churn. A lot of gnome2 stuff didn't carry over if I recall and had to be reinvented for gnome3

Gnome 3 has been out for 9 years now, which is longer than the time between the releases of Gnome 2 and 3. I don't think there is a lot of config churn. (It may have been worse in the early days of Gnome 3.)
