Nobody ever split /bin etc. "into" /usr; the historical standard was
to have those directories to split things "out from" the equivalents
under /usr.

Unclear; say "but this justification no longer applies today".
Preferably this bald assertion would go with a link to an explanation;
and I suppose that has to be
https://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge
(unless the Debian Wiki version suddenly gets much better).

Unless the plan is for the bookworm Release Notes to tell users with
legacy layouts that they can't upgrade, we should be pointing at
usrmerge here.
