There's also the "who cares?" factor. ;) Some things can get a bit overboard, and there are plenty of things Adywan isn't bothering to change that others might. I'm still surprised there aren't any full post-ANH:R edits out there, using ANH:R as a base. (using the best ideas from the 'Can anything be done after ANH:R' thread, perhaps)
I'd like to see Vaderios make an edit, but he doesn't seem interested in such a thing. (plus, a lot of mock-ups would be nigh impossible to put in motion, right?)
