Even if you get a crispy set of requirements from all parties you are still responsible for implementing all of then while making sense of the existing system (and from my experience significant issues arise at this stage when the full extent of requirement implications ia better understood). On top of that you might also be responsible for operating the thing, participate in compliance doc writing and do ongoing maintenace.

Yes, these things reduce (not necessarily how to zero) how much compliance the programmer is doing. They aren't figuring out how to get a car legally on the road, they're still figuring out how to get a car to do car things. The compliance questions the engineer sees are largely engineering questions. Sometimes hard engineering questions.
