Wasn't that scene shot after principle photography simply because it was an FX shot?

Bingowings:
Picking up the pieces could turn our heroic Alliance into a government just as bad as the Empire (Lucas is nuts for ending the story with Jedi, there is still so much more story to tell).

What would be the point of that story, though? Wasn't the story we have about that already? It would just be repetition. As much as I'd probably enjoy three post-OT movies, I do accept Lucas' assertion that this is about fall and redemption. The existing six movies work together as one whole, a new trilogy couldn't fit like that. It would be lile Babylon 5 Season 5, and I can do without another one of those.
