 I have a custom user model inheriting from `AbstractUser`. I set `username
 = None` because I don't care about usernames. I care about emails. Anyway,
 whenever I do that, I get an error message from the `manage
 createsuperuser` command.

 For example:

 {{{
 TypeError: UserManager.create_superuser() missing 1 required positional
 argument: 'username'
 ValueError: The given username must be set
 TypeError: StudentManager._create_user() takes from 1 to 3 positional
 arguments but 4 were given
 }}}



 This has forced me to customize the `UserManager`:

 {{{
 class MyUserManager(UserManager):
     def _create_user(self, username=None, email=None, password=None,
 **extra_fields):
         email = self.normalize_email(email)
         user = self.model(email=email, **extra_fields)
         user.password = make_password(password)
         user.save(using=self._db)
         return user

     def create_superuser(self, email=None, password=None, **extra_fields):
         super().create_superuser(email, password, **extra_fields)
 }}}

 My rationale for not having or requiring a username is that all valid
 email addresses are unique. I think the `createsuperuser` command ought to
 be more lenient in regard to the `username` field.
