Now that it is possible to move category pages, the "move-categorypages" permission needs to be removed from the user group (maybe others?) on some wikis, where the "move" permission was also removed. Otherwise, non auto-confirmed users will be able to move categories (while they are not allowed to move any other page)
The check for move-categorypages is in addition to the check for move, not instead of it. If users can't move regular pages, they can't move categories either.
