I could be misremembering, but I think the reason we added box reordering to XUL initially was for column reordering in multicolumn lists and trees.

It doesn't feel like a feature that should be specific to flexbox, so I really think it should just be cut from the flexbox draft and put in a more generic place.  It doesn't make sense to me to support box reordering but only for flexboxes.  If we're going to do it, we should do it for everything.
