According to the [documentation](https://docs.djangoproject.com/en/2.0/topics/db/models/#abstract-related-name), related names must be unique. Again according to the [documentation](https://docs.djangoproject.com/en/2.0/topics/db/queries/#backwards-related-objects) the default value, (if not set explicitly by the developer) is `FOO_set`, where `FOO` is the source model name.

So if I have two foreign keys (pointing to two different models, of course), wouldn't the (default) related names be similar?
