Dear lazyweb, I have a GitHub (mono)repo with a bunch of CI implemented as GitHub Actions. I want to move away from GitHub's godawful PR review design towards a sensible system which enforces one commit per review cycle, e.g. all the goodness of Gerrit plus Zuul for CI and policy-based merges, but without having to rewrite CI from scratch or lose branch protection. Is this easily doable? Tools like spr and ghstack for stacking 1-commit PRs only solve part of the problem.
