A Harrier can hover. Hovering doesn’t require that much in the way of thrust. Everything that modern jets do to hover can be applied to spaceships. At high speed, they put the majority of their power into shields that give them an aerodynamic shape. At low speed, they can rely on thrusters. The thrusters are nerfed, so even putting all your power into them doesn’t give you the control that the shields would give, but it would give you a different style of control.
To a degree, spaceships would have the choice of helicopter or jet controls. That might make for an interesting toggle on ships.
As for the observations about stability, the shields can be as magical as we like. If the shields provide the aerodynamic shape, then they can also subtly warp and twist as needed to provide aerodynamic stability.
The shields could also do things like form a razor-sharp disc around the spaceship, letting it fly “backwards” or “sideways” at high speed. There are all sorts of control modes possible when magic technology gets involved.
So the real question is one of what people want. Flavien presented his poll in terms of “realism” which I think is the wrong question to ask. I think the actual question is whether people want to keep flying the ships as if they were in space, as helicopters, as bullets, as jets, as dirigibles, or as something else altogether. Perhaps atmospheric flight should be a microcosm of space travel, where you fly like an airliner from point to point, then fight as if you were in a helicopter. Many things are possible.
