It's the same as any other PR. Keep the changes small and contained to that feature. AI can do this if you instruct it to, there is no need to vibe code some 40k line monstrosity.

Having unmaintainable code faster is only an advantage if it's a one-shot throwaway artifact.

Assuming we are measuring time and

`total = dev + review`

If dev approaches zero, but you review at the same pace as you always have, are you in a better position? Yes.

Will you potentially have a backlog of code waiting for review? Also yes.

Would you prefer to be waiting for the dev team for all of the time instead, then still have the same amount of reviewing to do at the end of it? Absolutely not.

Yes, but it's the only option if you want to retain a maintainable code base. And you can always slow down. You'll probably still be a bit faster than you were before.
