No, it won't.
Just try for yourself if you don't believe me ;-)

(hint: read /etc/init.d/rc, line 244ff)
In short: When you switch from one runlevel to another (say 2 -> 0),
/etc/init.d/rc won't run kill scripts if they already exist in the
previous runlevel.

That is actually not a good approach, because on every package upgrade,
the symlinks are recreated.
For more info read the update-rc.d manpage.

The problem is, that the expected behaviour is not defined by the policy

Huh? I know that of course.
I was referring to the avahi daemon start script:
... the avahi-daemon (dbus start script
/etc/dbus-1/event.d/25avahi-daemon) has become a SysV init script...

Make that a "has been changed into" if you prefer.
