Why is Mavic like that? I always thought the various freehub bodies (in this case Shimano 9/10) were generic, regardless of the hub they were fitted on. Why and how is Mavic different?

For what it's worth, my old wheel is Mavic (Aksium, a nice wheel by the way), but since the cassette is staying on there, it isn't an issue for me.

Thanks again to everyone for the comments.
