Following this checklist

---

Before submitting the PR make sure the following are checked:

• [x] Feature branch is up-to-date with main (if not - rebase it).
• [x] Squashed related commits together.
• [-] Added tests.
• [-] Updated documentation.
• [-] Added an entry to the CHANGELOG.md if the new code introduces user-observable changes.
• [x] The build (bundle exec rake) passes (be sure to run this locally, since it may produce updated documentation that you will need to commit).

I have no idea what 10/10 required status checks it tells about.

Do you want to be able to push directly to main?

Not really, I'm fine with such small PRs, let's keep main protected from sudden mistaken pushes.
