A maintainer wants to replace required human review with Copilot code review because the last ten generated patches passed CI. What is the best recommendation?

1. Keep human review only for patches written without Copilot.
2. Use the length of the generated review as the criterion for bypassing human review.
3. Use Copilot feedback alongside the existing review and test requirements, especially for consequential changes.
4. Require two Copilot reviews instead of one human review for every patch.
