I could go either way with the eyebrows. Removing the eyebrows makes more sense since Ady has included the PT lore in the edits as Ash brought out. From that stand point, he was burned with lava. Looking at Vader’s bald head shows the damage removed all his hair. Eyebrows are hair. So to me it would make sense for the removal.
However, I would not really care that much if the eyebrows stay. Not as important compared to the list your provide Valheru … I agree with pretty much all of it. 😃
