Such ability is good for people who prefer to do everything manually.
There are many of such people, so the ability as such is a good thing, but
I doubt whether any automation like the 'setup' utility can use it somehow.

Good hint, thanks.

Well, my point was not about how the reconfiguraiton is actually done (I
agree it should always go from scratch). I rather mean that IF there are
some rules in the system that are saved with 'service iptables save', but
are having nothing to do with the tasks solved by 'setup', THEN these rules
should be left as they are, may be notifying the user about their existence
with the ability to view/edit the new configuration.
