I think it translates roughly as "we aren't restoring those versions."

No I don't think so. They probably send a similar email to all people who ask for a title with no re-release date. I was more emailing them to see if they'd say something along the lines of, "Star Wars Episodes IV-VI are already available..." or something like, "The current versions of the films are the official versions." The fact that they referred to the unaltered versions as a separate product, and as a part of their catalogue is actually a fairly reassuring statement in my book.
