Perhaps things would be clearer if we merged 4.2.2 into 4.2.1 - that
is, instead of "Upgrade to Debian 12 (bookworm)" and then "Upgrade to
latest point release" (which doesn't really make sense as a separate
stage), combine the two as

 Start from the latest point release
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 The procedure given here assumes your system has already been
 upgraded to the latest point release of Debian |OLDRELEASE|
 (|OLDRELEASENAME|); upgrades skipping releases are not supported.
 Display your Debian version with:

 .. code-block:: console

  $ cat /etc/debian_version

 If needed, upgrade to Debian |OLDRELEASE| first following the
 instructions at |URL-R-N-OLDSTABLE|.
