I think if the Biomes shot were to be included, a lot of color grading and VFX to change the landscape would have to be done since the Mustafar atmosphere in Biomes is based on Rogue One, not The Rise of Skywalker.
Our current shot is literally modified Rogue One footage so I don’t see this being a big deal. This is the one change I’m really hoping will make it in time for v2.
