Gnome 3 has been out for over 10 years (12, to be exact). At this point if they change the UI there would be people like you saying "can I get back how it has been for 10 years?".
I don't really understand how we can have a so strong resistance to UI changes among IT professionals. Personally I started using Gnome 1, then moved to KDE3 when Gnome 2 was released, then moved to Unity with Ubuntu and now Gnome 3/40, Ubuntu flavor as well. I also used XFCE for a year or so at some point. I just need a month or so to get used and configure it a way I feel natural, and that's it.
