Maybe it is because they've read over RFC1912 Section 2.1:
" Many services available
on the Internet will not talk to you if you aren't correctly
registered in the DNS.
Make sure your PTR and A records match. For every IP address, there
should be a matching PTR record in the in-addr.arpa domain. "
If you feel that the way you use DNS is broad enough, why not write up
an RFC?
