@abrahamguo did you mean to keep this as draft?

[abrahamguo]

Yep! Still have to integrate the second PR. Working on that now, hoping to finish it today or tomorrow 👍

[JoshuaKGoldberg]

LGTM - very clean and straightforward. Yay!

But given that @kirkwaiblinger authored >1 of the linked PRs, I'll defer to Kirk. 😄

[kirkwaiblinger]

Looks good to me! Thanks for doing this!
