XFCE comes from the time...
...when GUIs were tested on people and usability was measured. Unlike the GUIs of today which come out of the minds of some deranged people trying to shove down something down your throat they saw on Android/iOS/Blackberry/WinPhone.
XFCE may not be at the optimal position with that, but at least it still tries to be usable.
