This is an often made misunderstanding.
Gtk (and every other GUI-lib) only implements the V (and sometimes the
C) in the MVC-Pattern. Gtk.ListStore is not a model in the meaning of
the MVC pattern!
One advantage of the MVC is that you can replace each layer/component
with another one. This is not possible when all components of the MVC
pattern are impelmented with the same lib (e.g. Gtk).

For example imagine: You want to replace the Gtk-View (Gtk.TreeCtr) with
another GUI-lib, or with a VirtualReality view or just a audio-view
(speak the content of the Tree).
