I don't really have a dog in this fight about TCP 53. It does seem to me
that it's a bit black and white to treat the RFCs as religious texts.
It's important to follow them wherever possible, but frankly they don't
foresee the bulk of the future security issues that usually materialize.
So if a feature of the RFC isn't working for you security-wise, I
believe it's your call to break with it there. As someone else said,
don't complain when it breaks other things as well however.

I think its possible to disagree without calling other folks stupid...
