IMHO that exceeds our objetives and those of the debian developers. I think is not debian's objetive to enforce a well structurated internet, which is not. It's by far more important that our operating system doesn't act weirdly when it shouldn't. Not to mention givin unecesary headaches to netadmins. And denying network services, wich might be crucial. Let's think in usability first: I don't like my servers denying conexions to clients ( wich could keep my company from making money or giving service to customers ). Is that supposed exquisite-security-enhacement worth denying a lot of conexions, with the consequences that this might have?
I strongly believe that the answer is NO. And so it should be removed, and left as an option for PARANOID netadmins, which want a false feel of dns based security.
