LGTM, thanks for your contribution.

Please don't merge main when it's not needed. It creates unnecessary email spam.

Hi, sorry for causing email spam. I just wanted to make it ready for merge since it had received two approvals. I’ll definitely be careful about that in the future.

We're currently waiting @tansiret to review this since he's a codeowner. If he doesn't, we'll merge this automatically when the PR is two weeks old

If a PR is not ready for a merge, the same spot that says to "Update branch" will instead say that there's a merge conflict. In that case you do need to act.
