Yeah, I can believe that Lucas himself doesn't want to release the original versions. They are, however, in my opinion of historical significance. They should be preserved.
I do have the original versions myself in a format that I can no longer watch. VHS.
One day, I'm hopeful the original versions will be made available again.

Additional material can be fun. I still laugh if you watch Galaxy Quest on DVD, and change the language from English to Thermian for all the dialogue.
Additional commentary, additional unreleased scenes, and behind the scenes are always welcome.
Sometimes additional scenes point to a different direction not taken, such as with Supernova.
Unfortunately some movies went to the well a little too often with their extended edition, special edition, ultimate edition, etc. I must have 4 different versions of Terminator 2, Blade Runner, and a film I didn't care for no matter what the version-- Alexander.
Sometimes the special editions are better. The Abyss for example. Zack Snyder's Justice League was a better version too.
Mad Max: Fury Road's Black & Chrome Edition was okay. Not sure it was needed.
