I’ll actually throw my hat in the “keep the eyebrow removal” ring. It makes more sense given how Anakin ended up in the suit for him to be eyebrow-less.
Though Rebels did depict him with eyebrows, so…
If it’s only there as a tie back to events in the PT then I am completely against it and would rather just see what was always there until GL changed it. IMHO, OT came many years before the PT, therefore the OT should have been the movie to stay the same while the PT needed to mould itself to fit with the long established originals, rather than shoehorning in such changes as removing Shaw’s bloody eyebrows LOL!
