Or consider codex low-code type use cases. Yes you could generate generic code, but integrated into some kind of platform that knows what APIs your company uses (internal cataglog) and some kind of IAM/Auth platform, PAAS to host the results integrated into a single tool might make sense, especially if the prompts are already injecting the boilerplate about how to interact with the ecosystem.
