docs: Deletes all objects that matches to the queryset.
  
          Note:
              Unlike RDBMS systems, this method makes individual save calls
              to backend DB store. So this is exists as more of a comfortable
              utility method and not a performance enhancement.
  
          Returns:
              List of deleted objects or None if *confirm* not set.
  
          Example:
              >>> Person.objects.filter(age__gte=16, name__startswith='jo').delete()
