25160	Move unsaved model instance assignment check to model.save()	Tim Graham	Aymeric Augustin	As proposed in the last comments of #10811, some people wish to use the ORM with unsaved model instances so it's been proposed to move the data loss check to the `model.save()` method. Such a solution would require additional consideration for `bulk_create()` since `save()` isn't called in that scenario. I've attached an initial patch to give an idea of the changes required.
