Nah, we already got all the stuff from the event anyway, or will be able to get our missing pieces on the official revival. So I see it more as a nice bonus for those who missed the original event.
I find it interesting how the game kept track of our progress during that event for almost a whole year though, it's really redundant information since we weren't supposed to ever see these maps in this state again. If it hadn't accidentally popped up again now, that data might as well had been deleted.
