I agree with your second paragraph, but I also think that as with every book, you have to understand the context it has been written and it is always good to have a wider picture and know how something can implemented using a different paradigm and how things relate to each other. I am not sure I can agree with the claim that everything written is following some design pattern. Perhaps it is an known anti-pattern instead or completely ad-hoc solution that is neither but is nonetheless a good design. Design patterns are architectures that have been distilled from the field experience to be useful to solve certain problems resulting in a good design. Therefore it is also quite natural that they get integrated into language designs over the time.
