It wouldn't be the first time that accuracy has been sacrificed for playability... A space sim that fully relied on Newtonian physics would probably be quite tedious and difficult? (In fact, I think one of the previous Frontier titles was guilty of this)
That said, I do believe Elite: Dangerous does allow you to adopt an advanced mode that might be closer to what you are expecting.
