It's not called the central dogma of biology for nothing!
But seriously, in my understanding it's taught that way to try to rid people of mystical pre-evolutionary notions. Once they have firmly grasped the basics they can move on to super-interesting corners where stranger things may happen, and about which people are still arguing.
The physics analogy is people arriving with mistaken intuition about "when does the dead body roll out of the truck" level problems. The fact that Newton isn't the end of the story doesn't spare you from having to un-learn Hollywood/Aristotle first. Nor will your earlier confusion be any help in wrapping your head around post-Newton concepts.
