I wonder if there is a voting for desired features/fixes/changes on github. Because changing that kind of default behaviour would receive my vote. Codeowner should be able to merge pull requests without review or, better option PR from codeowner should receive codeowner's review vote automatically.
Let's say we have three codeowners and we want all codeowners to approve changes. So we set that there should be three reviews from codeowners. Then if codeowner creates PR changes only repository admin can merge such PR, becuase it is not possible to get three reviews from codeowners.
I should add that it's super easy to set up code reviewers in Microsoft TFS. You can set up a minimum number of reviewers, specific single reviewers, multiple reviewers, required review from users in a group, etc. for directories or specific files. Here's their documentation. Would love to see this or similar funcationality in GitHub!
It won't resolve the issue.
We want to give the ability to merge the pull requests without review or with self review for specified users. But github doesn't allow it. The disabling of the mandatory pull requests is also not suitable for us. We want all changes to go through pull request and without direct pushes for everyone.
