I would suggest to do the same as we did with disallowing DROP in the 
nat table:

 - a message printed by iptables whenever -m state is used

 - a kernel message whenever whenever a rule with xt_state is created

We did not actually do the kernel side with nat-prohibit-DROP, but I
regard it as very useful, as the community was very much able to help
itself if only they got the word - and it turned out that dmesg is
_the_ place people look in especially when they don't supervise
iptables output directly, as with, for example, boot splash where
messages are hidden, or server/router devices that one tends to
forget about.
