Comment:

 The Django public API has hundreds of methods that can crash if you
 provide it the inadequate type, we can't gate them all with `isinstance`
 check.

 Unless you can provide a real world example where this is an issue (e.g. a
 documented use case that isn't explicit about a proper app label needing
 to be provided) I don't see the value of peppering this particular API
 with instance type checks as there are projects that provide typing stubs
 for Django already and [https://github.com/typeddjango/django-
 stubs/blob/87a23420767475ca3021f4f1a25887d3477d3dbb/django-
 stubs/apps/registry.pyi they have pretty good coverage for this API].
