Granted, Disney hasn't been great about putting out faithful original versions of things (Lion King, etc.), but a lot of their changes are to mask questionable content, so who knows how they'd handle the situation Star Wars is in (and Fox still has rights to Episode 4, which is another matter).

Disney didn't include the Special Edition Version of The Lion King on the 2011 Diamond Edition Blu-Ray. The Director's wanted to feature only the Original Theatrical Version from 1994 but of coarse with minor improvements to some of the animation and minor changes made to the some of the colors. In fact Co-Director Roger Allers said he intended to make some minor color changes. The morning report song was included as a special feature.

Even the 2010 Diamond Edition Blu-Ray of Beauty And The Beast contains all three versions of the film. The only drawback is the Work-In-Progress Version is a picture in picture presentation so if you want to watch it in full Anamorphic Widescreen you'd have to watch the DVD copy.

Disney seems to care about the preservation of classic films including all versions if a film happens to have more than one.
