29898	Adapt schema editors to operate from model states instead of fake rendered models	Simon Charette		"Rendering models meant to be passed to the schema editor during the migrate phase is the main source of slowdown during the migrate phase of a project. 

Adapting schema editors to be able to perform the same operations with model states would be way more efficient as model rendering could always be delayed until it's a necessity such during the application of `RunPython` operations.
