Bullshit!
You tell me how it makes sense for a second that she’d have that flag in her possession. And don’t try and justify it with some other piece of media explaining the flag’s origin. In the context of the film, it’s Anakin’s flag and nothing else. I think it’s a change that makes sense.
That, and I think you’re overestimating how much the prequels would really have an influence on the current state of affairs in the in-universe galaxy. Or are you complaining about lack of world-building while also arguing they should visit more planets we’ve already seen before!?
