What if this were dealt as part of firewall rules ?  i.e. GENERIC was built 
by default with IPFIREWALL and firewall_enable="YES" and 
firewall_type="OPEN" were set. That way the behavior that people have come 
to rely on is still there for those that need it.

I have not tested this yet with my production transparent proxies but I 
will try so later today to see if the behavior is broken as a number of 
people have reported.
