Hello here, I think we (including myself) dropped the ball a bit when cherry-picking some of the last weeks PR - resulting in unnecessary release managers (Ash's) work when he had to fix some issues in v3-0-stable and I had to also make the `v3-0-test` green to generate constraints.
I think there are a few things we should pay attention to that are relatively quickly merging cherry-picker's PR when they get green (or manually doing it if they cannot be done due to conflicts). I think (not sure) it's mostly on the commiter who merges PRs - they should see the follow-up comments from the "cherry-picker" and either mark the PR as "Ready for review" and merge it when it gets green., or manually do cherry-picking and resolving conflicts (and also merging it when it gets green). This is quite important - regarding the sequence of merging the - and doing it "relatively quickly" - because there might be other PRs that might depend on the already cherry-picked PRs - so they might be easier to be automatically done by cherry-picker. Also - waiting for the PR to get green (and either solving or asking for help if it's not) is important because it saves the release manager a lot of work on figuring out why v3-0-test and v3-0-stable is "red". And it makes it easier for the others who cherry-pick PRs after because it avoids their "red" cherry-pick that they have no idea where it comes from. I personally dropped a ball on it over the last few days / weeks and I am as guilty as anyone else with merging things too quickly - but also I saw a number of cherry-pick PRs that looked abandoned for a few days even if all they needed were to make them "Ready for Review". Maybe a good idea to pay a bit more attention to those when we are merging PR that is supposed to be backported. J.
