Rebased and conflict resolved. Updated using `RewriteResult/RewriteError`.

This is a friendly ping. Three months passed. @ytmimi Could you have a look? Let me know if I can help.

I understand your situation. (But... I wonder why don't you add more reviewers? It looks other PRs also are stuck with review.) OK. Then, I'll pause to make this PR...

@ytmimi Friendly ping in 2024 year end. I happened to notice that you are reviewing some PRs. Do you mind to take time to review this PR? I rebased it...

Thank you for taking time! FYI, it's a blocker for me to upstream it because I need it for CI. I don't want to diverge it.

Thanks! Comment added. All review comments resolved. (I'm not familiar with GitHub and a way of this repository. Which should I or you do `Resolve conversation`? I'll leave them.)

Rebased to current HEAD (fd0ea74) for projects using 2024 edition.

I'm planning to investigate it.
