Not sure about game development, but it sounds like a specialist programmer could become a dabbling audio engineer or narrative writer if given the opportunity, or vice versa. Might be a management problem: on a team of ten, you can grab the writer (singular) for coffee and spend a couple of days designing and writing dialogue for a side quest yourself, but on a team of hundreds it must be a lot harder.

And then, once you've spend that time using the tools, you can refactor the SpeechOptionNode to incorporate skill checks without attaching a script, or whatever other obscure tooling problems the writers are dealing with.
