I can see in journalctl output:

and the corresponding bugs 1039171 and 1039367 say: "This
is in the process of being deprecated and will be removed
by the time Trixie ships, so the remaining packages that
^^^^^^^^^^^^^^^^^^^^^^^^
ship init scripts without systemd units will stop working."
What's the status of such packages?
