Am I not right in thinking that this will only work if the component 
inherits from Catalyst::Base or at least one of its new friends? It's 
only for them that the automatic instantation in Setup occurs?

I think there's a real potential source of confusion here. For example, 
a classic catalyst view or controller is typically a singleton object, 
and one can get away with confusing class and unique instance. However, 
a CDBI or DBIC model doesn't work like this: an instance represents a 
tuple (row if you prefer) in the database. So what 'instance' would 
C->model() return?
