You're right - in the OT, the shot would be very steady. But in the OT (and Phantom Menace, if we're going to be truthful), the shots were mainly done with models - which, by nature, already looked real.
Almost everything in RotS is CGI. And even though we have a relatively smooth shot like we might see in the OT, everything looks fake. The only way to make it look LESS fake is to make the shot appear as though it was filmed on-location. In order to do that, I added the wobbly camera effect.Though I'll go back and forth and see if it's really needed so severely.
The best option would be to entirely re-composite the shot with actual models, but that's far from feasible, haha.
