Please do test it, but in any case please don't install before the
emacs-29 release branch is cut. This change is significant enough to
not risk it for the upcoming release of Emacs 29.

This needs a NEWS entry and a suitable change in the ELisp manual.

Andrea, can you please comment on the above question?

This variable should be documented in the ELisp manual and mentioned
in the NEWS entry.
Thanks.
P.S. It would be good to add tests for this new feature; see the test
suite we have in tests/.
