regardless they are Harmy's choices to be made.

No, things like that were Lucas' choices / oversights (or someone else on staff) prior to the movies being initially released.... because it was in the original, it's in this as it was.

This project's purpose is to restore the original theatrical presentations as faithfully as possible given the constraints of the sources Harmy is working with. It isn't to correct "errors" in the originals. Everything in the originals, "errors" or otherwise, are important parts of the fabric of the original releases.... and that's what he's trying to recreate.

Color timing is another issue. I have my own nitpicky bullshit when it comes to the color timing, but I don't doubt Harmy is trying to duplicate what he believes was the original color grading.
