I would agree with that if you'd put scare-quotes around the word
"security".  In general anyone depending on the reverse tree to
provide them any kind of security is engaged in wishful thinking,
particularly if the lookup isn't validated with DNSSEC.  (But yes,
that's waht the TCP wrappers package was supposed to be doing.)
