Comment:

 @mokhaled Thank you for opening this! Would you mind opening a pull
 request instead of a patch? That will facilitate reviewing and iteration.
 You can do so by opening a pull request for https://github.com/WordPress
 /wordpress-develop and, as the PR template instructs, but the URL to this
 ticket in the description to link it.

 Lastly, do you know of some plugins in the directory which would benefit
 from this? Last I checked, there weren't many, as I recall (which was
 surprising to me).

 Cf. [59823] which introduced this TODO comment for #61965.
