Everyone else made the arguments I was going to make.
Right now I'm against the burn marks. If you want to put them in an alternate version, that's fine, but they're just too distracting when the rest of the film is free of any dirt, dust, scratches, etc.; and as others have said, if George Lucas still had his marbles and LFL did a true restoration of the '77 version, with the original color timing and everything, the burn marks would not be there.
As with your earlier idea to add little bits of dirt and stuff, I believe that a "theatrical experience" version should be an alternate version.
Oh, and that thing in the TIE explosion is not a rip in the film - notice that it goes behind the explosion. My theory is that it's some kind of wire related to the explosion apparatus.
