Kurgan, you're a little off the mark in saying that many people were pleased with the 2004 DVDs. In fact, quite the opposite is true, hence why Adywan has undertaken this very project. Moreover, if one of Adywan's motives for undertaking this edit was to improve the visual quality of the film, then it wouldn't make a whole lot of sense for him to go and stick in a couple of scenes whose quality would be completely incongruous with the rest of the movie.

I sympathize with you in that I too would someday like to see an edit with these deleted scenes put back in, however this is not the edit for it to happen in. Until then, if you like vintage Star Wars and like getting more detail/backstory, you should check out the Star Wars radio drama. If you haven't heard of it before, it's a 13-part radio series produced in 1981 that follows Lucas' earlier versions of the films in that the story starts off by following Luke Skywalker, and includes the dialogue which you posted earlier between Luke, Biggs, Fixer, Camie, and company at Tosche Station. It's quite excellent in terms of its production, and even features the voices of Mark Hamill and Anthony Daniels, as well as John Williams' score and Ben Burtt's sound FX.
