Description
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.
Ref #22608.
