I think there were some good counterpoints to what you said. But the most important one is.. USER. People will record the video differently hence, adding more complexity to solving, comparatively, a simple problem. One person might do the movements really fast, which leads to blur, which would mean they now need to add de-blurring. Other person might even miss an angle that was required. I think this is likely why panoramas are made in parts.
