I don't think RTD is using django-guardian as one of AUTHENTICATION_BACKENDS. It is being used for its other functions/classes - assign, get_object_for_user, GuardedModelAdmin (class).
I grepped all the files, searching for guardian and I found only these uses of it.

Also, AUTHENTICATION_BACKENDS was introduced during the configuration of django-allauth ( #commit), much after the configuration of django-guardian (related commits: #commit1, #commit2)

I think I saw the same warning on production, so this shouldn't be causing any problems.
