I don't see why this always has to be performed. There so many ways
to break your system when you're root, so being required to define a loop
free rule sets after specifying some kind of "yes I really want to"-
option should be that much of a burden. As far as I understand
the code, the loop checking at the moment is done in userspace, so
nobody stops you from simply removing that part from the iptables
code.
