@csabella since your are the one who reviewed the previous PR, maybe you will be interested in reviewing this one as well? I understand that two years have passed, but nevertheless :)

Do you have some concrete use case for _shouldBeLoaded()? I do not like introducing yet one private method which can became de-facto a part of the interface.

Yes, I had some unittest plugins in mind. Examples:

# Some typical django project's tests:
from django.test import (
    LiveServerTestCase,
    SimpleTestCase,
    TestCase,
    TransactionTestCase,
)

class MyTest(TestCase):
    def test_sum(self):
        self.assertEqual(1 + 1, 2)

Now, let try to load these tests:

In [1]: from server.apps.main import tests

In [2]: import unittest

In [3]: loader = unittest.TestLoader()

In [4]: loader.loadTestsFromModule(tests)
Out[5]: <unittest.suite.TestSuite tests=[<unittest.suite.TestSuite tests=[]>, <unittest.suite.TestSuite tests=[<server.apps.main.tests.MyTest testMethod=test_sum>]>, <unittest.suite.TestSuite tests=[]>, <unittest.suite.TestSuite tests=[]>, <unittest.suite.TestSuite tests=[]>]>

I also know other projects that define unittest-style test helpers, including my own ones: https://github.com/wemake-services/django-test-migrations/blob/553725f88d8927a7be6b7d0ca916aac393c5a053/django_test_migrations/contrib/unittest_case.py#L13

But, I think it is fine to inline this for now, so we can later design a better API and refactor these changes to use it instead.

Let keep this change more narrow.

The idea about official method to exclude the class from automatic test loading already was discussed. Try to search in old issues. Although the issue where it was discussed may be closed.
