Changes between Initial Version and Version 1 of Ticket #18597, comment 5

initial	v1
	1	Transfering my concerns from the duplicate issue. I there is some code cleanup needed before attempting to fix this.
	2	This will at least allow people to extend existing base classes to create custom inlines that can do ( facilitating the feature in the core framework is secondary)
1	3	This would help support prefetching configuration on parent admin's queryset.
2	4	This is not sufficient to support prefetching since there are multiple (I have found at least 3) instances in inline admin and inline formset where `self.get_queryset()[i]` paradigm is used.
