Here's yet another can of worms:
In the early ROTJ trailers, Luke's lightsaber was not green...it was blue. It was colored green later.
The question is this: in this deleted scene, was Luke's saber blue like the early trailers, and did Lucasfilm color it in green recently, to match the final version? We may never know.
I dislike revisionism, and even more so in cut scenes, since we've never had access to the original even on VHS!. But the line between restoration and revision becomes very blurred at times, especially when you get into missing effects shots or unfinished scenes. Best case scenario would be having both the untouched/unfinished scene as-is, and then a restored/finished version as well.
