Hey, if you find that there are still edits to be made and have the will to make them, I say go for it. HAL9000 is STILL making minor changes to his prequel trilogy edits and they’ve been out for years and years now. I’ve downloaded several versions myself, because I only want the best possible versions of films that deep down I want to enjoy. The fans of any edit will likely always come back for the next version if the new edits improve the experience. Improvements are always welcome.
And your paraphrased Gandalf quote is a good disclaimer and you should probably just leave it at that.
