Your not overlooking anything, MenuItem, and CommandMenuItem don't have the same methods on them that Menu does. Basically MenuItems and CommandMenuItems can't have any children, because they aren't Menus, but once you've set subMenu=True, the item returned is now a Menu, it can possibly have children.
So another thing you could attempt, would be just duck typing the whole affair by wrapping your call to getNumberOfItems() in a try / except block that catch's AttributeErrors, these would obviously fail on MenuItems/CommandMenuItems, but would return properly for Menus, this would let you continue to use the PyMel convenience methods, and is certainly considered 'pythonic'.
