Looking through the commit history there are numerous “Manually fixed…” commits, where the LLM doesn’t do what the programmer wants after repeated prompting, so they fix it themself.

And here is the problem. It required expert supervision for the prompts to be repeatedly refined, and the code manually fixed, until the code was correct. This doesn’t save any labour, it just changes the nature of programming into code review.

If this programmer wasn’t already an expert in this problem domain then I have no doubt that this component would be full of bugs and security issues.
