I don't think this quite captures the problem: even if the code is functional and proven to work, it can still be bad in many other ways.

The submitter should understand how it works and be able to 'own' and review modifications to it. That's cognitive work submitters ipso facto don't do by offloading the understanding to an LLM. That's the actual hard work reviewers and future programmers have to do instead.
