I have never understood the principle to mean that.  I have no idea what 
the meme means, if anything.  If you want to write a document about how 
the Postel Principle is often misunderstood, and that such 
misunderstandings cause problems, I would have trouble disagreeing.
But that is not the document you wrote.
