That is an easy case: the package shouldn't ship neither a symlink, nor
any other override.

Though, there's one more case where a symlink/override is required: when
you're dealing with a package that implements a special service, such as
a syslogd: those need to register themselves as syslog.service.

It would only highlight the case where the /lib thing moved. Nothing
else - but that's still an improvement. And if one uses include &
overrides instead of copy & change, then bugfixes made to the original
are more likely to get used.

Pretty much how a snippet in /etc/default works - the init script
including it can change, and you get no notice at all if you didn't
change it. You only get notified when the /etc/default/$foo file changes

For important stuff, there's NEWS.Debian still, and then we don't need
any special tool.
