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.
Wow this actually makes a lot of sense; there are tons and tons of scored deleted shots from ROTJ for which we don’t have the footage, stuff I’ve never heard people talk about.
For example, the opening cue right after the title crawl, 1M3 Approaching the Death Star, has tons of trims totaling almost 40 seconds, and I have no idea what footage it was supposed to play under. When people think of the opening of ROTJ being cut, they think of the Luke lightsaber scene, but that had a different cue recorded for it, 1M4 Vader Contacts Luke.
