> Wasn't this whole discussion already had on the web with Postel's robustness principle? With the ultimate conclusion learned from the web generally being that long-term, tolerating brokenness leads to more interoperability, security and privacy issues than strictly refusing invalid configurations.

That is absolutely not true when it comes to security. Postel's law is widely regarded (at least by security experts) as misguided in a hostile world like today's Internet. (It was probably a good idea at the time, but no longer. Of course, in *some* cases it might still be a good idea.)

I think you misread. The passage you quote agrees that Postel's law has been proven unhehlpful on the modern network. It's just a bit hard to parse.
