> LLM-generated code should not be reviewed by others if the responsible engineer has not themselves reviewed it. To extend that: If the LLM is the author and the responsible engineer is the genuine first reviewer, do you need a second engineer at all? Typically in my experience one review is enough.
anyone who is doing serious enough engineering that they have the rule of "one human writes, one human reviews" wants two humans to actually put careful thought in to a thing, and only one of them is deeply incentivised to just commit the code.
your suggestion means less review and worse incentives.
