In order to display anything, it needs to be placed in a window. Your code above is correct in that it doesn't send -close to any status bar items, but it *does* send -close to the invisible window that constrains them. That's why they disappear.
You'll probably want to do some more careful checking of the windows prior to sending them -close. Perhaps check the class of their window controller or their delegate.
