PR authors should always have the responsibility of deciding when and how to merge their pull requests. There are lots of cases when that is not “immediately after it’s approved”. For instance, I might send out a PR for review before going to lunch, but want to make sure to do some extra end-to-end testing when I get back. A quick approval in the middle shouldn’t force it to be merged.

The stock UI _does_ have a big advantage compared to labels: the “Review requests” dashboard ([https://github.com/pulls/review-requested](https://github.com/pulls/review-requested)) shows you all pull requests for which you still need to provide a review:

This is, of course, properly integrated with the “Request re-review” action.

I check this many times per day (usually, multiple times per hour). Someone on my team at work proposed using this workflow about a year ago, and everyone got used to it in no time. There’s not really anything to learn; it works very well.

It’s a manual action, but it kind of has to be. You generally _don’t_ want to set the state to “needs additional review” whenever additional changes are pushed. In most cases, when you’re ready for re-review you’ll also be submitting a counter-review to respond address comments, so you’re already in the UI _and_ the action is top-of-mind.

I’m not sure why you’d want to find all the pull requests that have an approved review, but if you do, just filter for pull requests with approved reviews (equivalently, search for `review:approved`):

> If we agree to use labels for review state, it sounds like we could use GitHub actions to build automation to keep the labels up-to-date (set the label when there’s an approving review, reset the label whenever there’s a push, etc).

We surely could, but that’s automation that we have to write and maintain. Because it’s custom, we’ll also lose any familiarity benefits from people who are used to the normal GitHub UI. We’ll have to deal with awkward ACLing issues—external contributors can’t change labels on PRs (which is by design, because labels are often used to bless a PR to run on a trusted CI system), so how is an external contributor supposed to manually change the merge state if (e.g.) they realize that it’s not actually ready for re-review yet? Do we need to write a bot that responds to commands to change the labels? All this complexity really needs a compelling motivation to be worth its weight, and I’ve yet to be convinced that such a motivation exists.
