I need to double check the discussion back then, but I think the tests were pretty beta when initially merged.

So it was intentionally to not include them automatically when KUNIT_ALL_TESTS is enabled.

We can probably do that since the tests are stable now, but I think we should definitely drop the Fixes tag.
