That file is (and must be) a conffile. As such, you are incorrect:
The file is only updated if accepted by the local admin. And requests
for updates are only done each time the content of the packaged file
changes between installed and to-be-installed package.
If we want to change the default of the package from not starting the
daemon to starting it, then the correct approach is to simply change
the packaged file.
That way users updating the package are made aware of the change.
That's the point of conffiles - don't try to defeat that :-)

Correct. That's another uglines of this.
The maintainer of dovecot solved similar issues among the binary
packages dovecot-imapd, dovecot-pop3d and dovecot-common.
* dovecot-common provides sysV script
* SysV "start" action fails silently if binary does not exist
* SysV "start" action uses treats already running as no error
That last one bit me today: Some package other than asterisk itself is
updated in same batch as asterisk, restarts the daemon, and when
asterisk later attempts to start it again after updating, it fails,
telling to use restart instead.
