If I recally correctly, it was removed because it was decided that iptables
rules should be being configured through ifconfig's /etc/network/interfaces and
/etc/network/if-*{up,down}.d mechanisms, and pppd's /etc/ppp/ip*-{up,down}.d

Otherwise, you can't load only the relevant parts of the ruleset to match the
interfaces currently enabled, and you have to reload the entire ruleset if you
bring up interfaces later that /etc/init.d/iptables time.

And it keeps network configuration nicely together, in the one file, the same
way resolv-conf keeps static DNS configuration nicely centralised in
