That said Elite: Dangerous regular flight physics are still Newtonian, even more so than I-War series as it features rigid body dynamics and not a point mass, but the ships have very strong maneuvering thrusters a flight control system computer to counteract the skidding and keep it within a certain speed limit, but you can partially turn it off.

You can't say you follow some rules and then break them when you choose to and then say your game is Newtonian. Because then every game having player moving in the world is.
Here are the facts. When turning you keep you velocity, which implies magical thrusters that can change power drastically when needed to do so. But why not use that power all the time and not only when turning? Doesn't make any sense. And there is a maximum speed limit. How does that follow the Newtonian laws?
To be it seems awfully insulting that players wouldn't understand that a ship doesn't necessarily go where it's pointing, which is really what it comes down to.
