systemd-shim expresses no preference for init system, and is completely
coinstallable with systemd-sysv - and should be a no-op when booting under
systemd because the dbus name is already taken.

So the worst case is that you get an extra, inert systemd-shim package
installed on upgrade.  It's not going to cause a different init system to be
selected.

Michael, is it clear to you why this change is needed, and can you
un-wontfix this bug please, to list systemd-shim as the first ORed
dependency as I've asked previously?
