Submitter Checklist

• ♽ Run make test lint before submitting a PR (ie: with pre-commit, no need to waste CPU cycle on CI
• 📖 If you are adding a user facing feature or make a change of the behavior, please verify that you have documented it
• 🧪 100% coverage is not a target but most of the time we would rather have a unit test if you make a code change.
• 🎁 If that's something that is possible to do please ensure to check if we can add a e2e test.
• 🔎 If there is a flakiness in the CI tests then don't necessary ignore it, better get the flakyness fixed before merging or if that's not possible there is a good reason to bypass it. (token rate limitation may be a good reason to skip).
