That's a pretty general blanket statement that is most certainly
not always the case.
Consider (as a very basic example) a master/detail view (without the
use of Bindings, especially). Sure there're plenty of reasons I can
think of to have multiple controllers (one for the master list and one
for the detail view), but for every reason I can think of to
separate the controllers in this scenario, I can think of one that
strongly suggests keeping them as one.
The thing is, in this scenario they'd still need to talk *somehow*
(to track the master selection for determining what to show in the
detail view) and the model is *most definitely not* the place to track
selection in the master view. That is between the view(s) and the
controller(s).
