both by Apple employees, overlapping sibling subviews are fully
supported in Leopard (and presumably beyond).
Interesting. I hadn't noticed that discussion. I'm glad you
brought it to my attention.

Off to file a documentation bug...
The NSView class reference says:
addSubview:
Adds a view to the receiver’s subviews so it’s displayed above its
siblings.
[...]
addSubview:positioned:relativeTo:
Inserts a view among the receiver’s subviews so it’s displayed
immediately above or below another view.
I don't remember if the z-ordering was documented as guaranteed before.
I just submitted feedback using the link at the bottom of the NSView
class reference:
"The docs for -addSubview and -addSubview:positioned:relativeTo:
should make clear that z-ordering is only guaranteed starting in 10.5
(unless it was really guaranteed all along but you couldn't be sure it
always would be)."
