But...Elite is newtonian as well...
No, with that artificial yaw limit it is not. It may have inertia but it also goes out of its way to not play like a Newtonian space sim but more like an aeroplane simulator game instead. In a true newtonian space sim, there is little distinction between yaw and pitch and thus little incentive to use roll. Contrary to aeronautic simulators where it is crucial to use wing flaps or whatever to rotate and so yawing is not optimal. This leads to quite different play style. And Elite goes for this plane sim crowd. Which is fine I guess, it can also be fun to play for some people, but it doesnt scratch that Newtonian space sim itch for me. SC does.
So...you know nothing about how planes fly. So let's get that out of the way first. So when you say it caters to the flight sim crowd because you use roll as the most predominant axis, you don't really know what you're talking about.
Second, you can counter the limited yaw by rolling to the side, and thrusting downwards and pulling back, giving you a very tight turn radius.
Thirdly, it's great that SC scratches that itch for you, but for me it looks like a very weak combat sim. Plus I can't even play it, since the code is so poorly optimized I can't even run it on my system yet. So whenever they fix that, maybe I'll check it out. But so far that video you posted looks "floaty" (in the sense that none of the ships have mass), so it looks more like Descent than a Newtonian simulator. Just because you can yaw fast and fly backwards doesn't really make it a great space sim, but to each their own.
