What kind of Morph are you talking about? Are you just referring to 
subclasses of MorphicModel? Outside of these, there is no explicit connection 
between a separate model object and a Morph, so you could do things any way 
you wanted.

There are a number of calls to the model that expect a return value, so a 
pure notification wouldn't work in all cases. In this one case (deleting the 
Morph) it could work.
