The it doesn't matter what you chose and who you killed in the last game, and even though you imported a save from that game we're still going to ignore it.
That's a stretch, the game is aware of quite a few decisions and reflects the appropriately, but Leliana's magic rebirth is pretty egregious.
They've done worse. Right now, I am more than prepared to believe they are willing to ignore any decision the player makes or reasonably wishes to make.
