Either you allow LLM generated + human reviewed code or people start hiding AI use.

...and then people start going "that's AI" on every single piece of code, seeing AI generated code left and right - like normal people claim every other picture, video or piece of text is "AI".

IMO it's a lot better to let people just openly say "this code was generated with AI assistance", but still sign off on it. Because "Your job is to deliver code you have proven to work": https://simonwillison.net/2025/Dec/18/code-proven-to-work/
