Not referring to that actually, I think that was actually a great bridge to Ep 4 that helps put the story in context for casual fans.

More the presence of the Force and Jedi lore. They were so close to not having that be part of Rogue One but were still forced to include the mystical super beings in some way. Andor was able to fully detach from that baggage, focusing on the little people doing their part. And when they did bring in the Force healer in the second season, it was exactly how you'd expect average people to respond to a mystical power that you didn't directly witness. Hope, faith, skepticism, denial, rejection.

As far as Vader goes...it does make you wonder if he's just toying with Obi-Wan when he meets him like 3 days later...
