Following Postel's law results in the normalisation and proliferation of defective implementations. The actual standard becomes irrelevant, and new implementations have to be coded against the defective ones.

My opinion is that Postel's law should be approached in the same way that Linus Torvalds did CVS when designing Git. If in doubt about an implementation decision, consider what Postel's law would recommend, and then do the exact opposite.
