Yeah, I suppose so, but I imagine it's hard to know precisely what sounds were sent to the other channels and at what volumes at all times from even a recording made in a theater. So the 70mm stereo version is a more conservative approach, since no judgment calls had to be made on what was correct and what wasn't. Just remove the changes placed in the DC laserdisk soundtrack with the unaltered soundtrack from the previous laserdisk set and you're done. It's nice to have the option for both. :)
