If you ask an LLM to review your code, then it tends to write a lot of code for situations that will never happen. You choose the bits you need. It's actually pretty useful as a code reviewer.
If you don't review the review, my assumption is that it will add a lot of code bulk, which won't break anything now but that bulk could soon fill up context windows and/or require far more tokens in future when you want to maintain it. You'll most likely end up with a project that human's can't maintain.
Code bulk and future maintainability really feel like unsolved problems, and we have no idea what tools or costs will be this time next year.
