I will say that inserting deleted scenes isn’t entirely unprecedented for a special edition, as proven with the ANH Jaba scene. But that scene really sucked, so it’s a good thing it got removed from Revisited.
If this edit wants to be the definitive remaster of RoTJ, I think that scene could definitely be cool to see. Especially since Vader reaches out to Luke in a manner very similar to Kylo and Rey speaking to each other from across the galaxy. I really like the idea that Vader could have been trying to form a dyad in the Force with Luke.
But it does take away from Luke’s mysterious appearance at the palace, I suppose. I dunno, I think I prefer being able to see somebody making a lightsaber in a live action movie over that, though. Also makes it more clear what the plan is exactly to rescue Han.
