That’s what I said. Since it’s just one scene, they should provide the full 1.44:1 framing inside a 1.78:1 window (pillarbox) and as a SPECIAL FEATURE. In this way we can see the framing as originally intended and those who complain about shifting ratios can watch the film matted to cinemascope throughout.
However, I would look forward to the 2.39 to 1.78 shift on the 3D BD and try and be satisfied with it since I don’t have an IMAX theatre of any kind nearby and have not seen that particular version. I will say though, that when the Falcon is doing that flip before the cameras and the Two TIE Fighters are coming in from the opposite direction, it was very clear that J.J had composed the movie for a narrower aspect ratio and wanted the Falcon to almost touch the top and bottom of the 1.44:1 frame, to give a life-size scale to Han’s ship.

In the 2.39:1 version that scene felt TOO TIGHT due to the vertical cropping and almost indiscernible.
Same with the shot of Rey, Finn and BB-8 running -
Both shots felt TOO TIGHT in the widescreen version due to them being a straight vertical crop. If J.J would have adjusted the framing, say taking the full width of the 15-perf frame for the scope version and for the IMAX, zoom-in slightly and cut off some image at the sides. But to do that he’d have had to plan beforehand and shoot the scene from a distance. It’s very clear that J.J was composing for 1.44:1 in mind and the scope crop was just a compromise.
Even on the 1.78:1 IMAX scenes, the shots will feel tight because you will not be able to see the full Falcon or Rey’s legs within the frame which would have subconsciously created the immersion effect in our brain.
