All this to say I think it’s fallacious to take the blu-ray deleted scenes totally at face value, as in many cases they seem to have been taken from random post-production sources (sometimes not even for the scenes taken from out and out dailies) and cut in a way to actively discourage attempted fanedits. That does not accurately represent the scene in the scoring/preview cuts, I’m sure, but a much earlier stage in editing.
Different film, may not apply here, etc - but I do like the theory that, at least with ROTJ, the material on the Blu-rays is actually the footage that didn’t make it into any rough cut. Thus, when one of the Lost Rebels has a cut in their footage, that’s because they took out that particular line and put it into a rough cut.
