As I understand the code in django.db.models.fields.related the _add_items method of ManyRelatedManager takes care that the same object isn't added twice.
So I suggest to document that in /ref/models/relations/#django.db.models.fields.related.RelatedManager.add, maybe like this: "Adding a model that is already in the related object set has no effect, it won't be contained twice afterwards."
(I looked it up in the code, but just a year ago that would have been difficult for me.)
