That is quite sad if this is true. I would have never submitted a PR without knowing everything about the code I had generated. I manually looked up the RFC for test vectors, because the LLM sucked at it, and I generated the tests and made sure it is correct and in accordance to the RFC. The test included edge cases, too, and all the tests found in the RFC. I had to know a lot, and do my own research a lot, for the LLM to be useful, to be honest. I do not think LLMs are there (yet at least).
