And I would say that sending an email is a state change, and behavior  
of the application domain here.

Again, I think that the sending of email from the application is _very  
much_ behavior. In future you may want to replace the implementation  
of it, or wrap it with extra functionality (e.g. to count the number  
of emails sent), or reuse it in an application context beyond the web  
app (e.g. sending email from a batch script).

With a model all of these things are not only possible, they're easy,  
and you've got a framework for the abstraction and use outside  
Catalyst already provided...
