  Postel's law is a good principle when your threat model is nature; it leads to
  robustness in the presence of random failures. But it is _not_ a good design
  principle in an environment of intelligently malicious failures, i.e., the
  internet. In other words, for reliability in uncertain but benign conditions,
  yes---for security, no!
