And wouldn't be difficult to achieve, just 'injecting' Model.type_field = 'a type' to all the find and creation queries.

I've done that before, and (as you would expect) so long as the class you want to extend is already loaded (either explicitly by your own code, or because it's loaded first by cake) cake wouldn't know or need to know there was a class in the middle.
