Request factory with a preset admin user

Wouldn't it be reasonable to have a request factory, which sets user field by default on every created request? Like admin_client does. For example:

 @fixture
 def rf_admin(admin_user):
     from django.test.client import RequestFactory

     class AdminRequestFactory(RequestFactory):
         def request(self, **request):
            r = super().request(**request)
            r.user = admin_user
            return r

     return AdminRequestFactory()

Because 90% of the time I use rf fixture I set admin_user on it.

Start by reading the existing rf fixture and the admin_client fixture, then inspect how Django's RequestFactory is used in the plugin's tests. Define the fixture's expected name and behavior, including when it assigns admin_user, and add coverage showing that created requests receive that user.
