People who discovered Star Wars in 97 with the SE would be upset to not have the possibilty to watch it. Well maybe some of them even ARE upset of the few (but horrible) new changes on the BR.
It would not be a big deal such as the missing originals, of course. Because "movie history" would be safe without any available SE. But still, I think it would also be a slap in the face of some fans to not present them in DVD and Blu Ray.
