Postel was widely misunderstood to say that you should try to accept
arbitrary garbage. People who knew him tell me that he meant to be
liberal when the spec is ambiguous, not to allow stuff that is just
wrong. As their quote from RFC 1122 points out, he also said you
should be prepared for arbitrary garbage so you can reject it.
Yeah, I read the pdf and I took away the same thing as John.

It may
become hard to reconcile this with the robustness principle
(Be conservative in what you send, be liberal in what you accept)
that Jon Postel popularized. Maybe it becomes necessary, though.
Yes; the LangSec people essentially reject the robustness principle.
