I don't quite understand why (although I agree that it's remotely possible),
so how about using -D instead of -A (or -I) with exactly the same parameters
as you specified when adding the rule?
eg: if you add a rule using
iptables -A FORWARD -p tcp --dport 80 -s 10.20.30.40 -d 172.16.17.18 -j REJECT
you can delete it using
iptables -D FORWARD -p tcp --dport 80 -s 10.20.30.40 -d 172.16.17.18 -j REJECT
Where it happens to be in the ruleset when you delete it is irrelevant.
