IIRC, only Spielberg has tried this same revisionist cinema with E.T., on the 2002 DVD, and at the last minute he relented to fan protests and put the original version in there -- decent DVD quality, anamorphic. But even so, seven years after that release, I had to track down that 2002 release and order it from overseas; the only version being sold now is the re-release.
Don't know why these two guys feel so embarrassed now about their masterpieces.
