Due to the way that Python and Django load modules, there's no guarantee that the models you need will exist at the time the form is loaded, which can lead to some interesting circular dependencies. This is the major reason why UserCreationForm and UserChangeForm are bound to the User model specifically. The good news is that you can still re-use the form logic in those two forms -- a form is just a class, so you can subclass them. If you User model subclasses AbstractUser, all the core fields have the same name and constraints, so all you need to do is redeclare the Meta portion of the class definition (to bind your subclass to your actual User model). This way you get all the logic for password/username checks, and the custom save() methods, but against your own model and field list.
