The ideal state alluded to is that Dev teams write modules that cleanly 'plug in' to the flowchart mess, but the reality is that a Dev team that can write code at that level (in a modern world, it implies at least an abstract/subconscious understanding of mid-advanced FP-ish concepts, including merging Procedural things like calling the bizarre webservice you're probably integrating with, while striving for idempotency based on the provided args/context.)

At that point, said devs likely are of a skillset they could build a framework for lower TCO, or at the very least are productive enough that they aren't the problem.
