Hi, Back in the Bugzilla days, only reviewers were allowed to r+ or r- patches. Non-reviewers were - of course - encouraged to do informal reviews but they would do so by leaving comments. They would never r+ / r-. Since we’ve moved to Github, it seems we have become a lot more lax about this and I have seen non-reviewers approve and reject PRs, not just leaving comments. My understanding is that there is no way to prevent this with Github but could we at least make it a policy that non-reviewers should not approve / reject PRs and only leave comments instead? The reason I would like us to make enforce this rule is that I find it confusing. We have a lot of new comers in the project and I do not always know if a person is a reviewer or not yet. I imagine it may be even more confusing for non-Apple people. I have in some cases not reviewed patches because I had seen the "green check” and thought the PR already had been approved. I have also seen cases of PRs rejected, asking the author to do more work, that I didn’t feel was necessary. There is no easy way from the GitHub UI to tell if the person who approved/rejected your PR is actually a reviewer, as far as I know. What do you think? Thanks, Chris Dumez.
