Okay, so what are you going to do with this iptables package?  As far as
I can tell, there are two options:
  a) nothing;
  b) iptables -P INPUT DROP; iptables -A INPUT -m state --state

a) provides no change over the status quo.
b) provides no change over the status quo, except that it encourages
people to have open ports.  It would mean that people who wanted to
listen to the outside world have to explicitly punch a hole in the
firewall.  Right now, people who want to listen to the outside world
have to explicitly open a socket on that interface, which to me is a
pretty clear statement of intentions.

I just don't see why you would want it.  How would it make things more
secure, at all, except for the warm fuzzies that come from having a
firewall?  It provides no practical benefit in any case which isn't
hopelessly contrived.
