Close Encounters of the Third Kind also has three distinct versions of the film on one disc. I think three versions is probably as complex as you'd probably want to go though.

The Star Wars blu ray release is a terrible missed opportunity for this kind of package. But then I think Lucas has always been a proponent of a streaming/download/non-physical media future for entertainment (shudders) which is why the Star Wars films always arrive on a new physical digital format *years* after it is introduced. I personally think they intended to try bypass blu ray alltogether but eventually it made too much business sense to put it off any longer. But like on the 2004 DVD I think this set is being done with the bare minimum of effort and expense and once again includes a token set of bonus materials that at first glance might appear rich but on closer inspection are actually just filler.

Lucas used Star Wars to get away from a studio system he felt was exploitative, technologically backward and artistically compromised. But who has a better track record of quality, richly featured and timely home video releases? The studio system.
