I don’t know, I still feel like it’s definitely new for Star Wars that they’re trying to entertain us with Slasher Vader. We don’t see Slasher Vader in the OT, and it’s not a coincidence. They could’ve treated Hoth like the Rogue One hallway scene, but they don’t.
An important theme in the OT, which is somewhat continued in the PT and ST, is that the dark side isn’t badass. It isn’t spectacular. It’s deranged and pathetic. It’s definitely a little different that Rogue One and Mando focus on both heroes and villains murking mooks.
