I don't actually mind plot holes like that as much for just the reason you said. I just couldn't think of any blatant plot holes based on things that were already revealed in One Piece. I have seen some of those in Bleach, though (especially the arc that is currently airing in the dub). You do make a good point about the lack of development. It's exactly the reason Xiao was so forgettable even though Strong World is one of the best One Piece movies.
