I am not sure I understand where claude is going with these changes. I think we need first some level of design sketch as that's a feature that's not popular and likely ai will get its design wrong. For example, we need to store some of the information in the PTU itself which can be used as an undo starting point.

I am not sure I also understand the codegen changes part, yet either...
