Well, they are two different things. On the one hand, for the archival master purposes, yes, you want everything in the scan to be preserved. And as Mike has pointed out, it's all there and recoverable and so on, so that angle is already taken care of.

Then there's the fully restored version that you sit down on your couch and watch on a normal 1920x1080p HDTV and looks just the way it was intended as Lucas sat there going over preview screenings getting the film ready for release (or as close as possible, given the sources available, uncertainty about exact color timing on certain shots and so on). With space being inky black and these mattes and such not visible at all even in a very dark living room viewing environment, etc. That's certainly the version I look forward to seeing in any Star Wars preservation/restoration project when I actually watch it for real in front of my HDTV with some popcorn and an ice cold Coke. :)
