I recently watched a DistroTube episode [1] where he explains the many problems (cultural and technical) with the current Linux desktop environments, and he is very critical of Gnome, in particular. As an Ubuntu user with a very Emacs-centric workflow, it was slightly surprising to me, as I am quite happy with my Gnome setup, and I was not particularly aware of this "war" waging in the GUI dev world. However reading your comment I realize that I'm not alone in appreciating the extreme simplicity of Gnome, especially when it's almost entirely keyboard driven (I do everything I need by invoking the Super key). Caffeine is also the only extension I use, and my happiness would be truly complete with a keyboard shortcut for it, I think.
