NSTreeController / CoreData still broken in 10.5?

A general question:

I have read a lot of discouraging posts on this list and out on the
blogs about the trio of NSTreeController, NSOutlIneView and CoreData.
Most of them come from the 10.4 era. Under 10.5 is this something that
is working better now?

A specific question:
A lot of the NSTreeController, NSOutlIneView and CoreData example
projects use a single entity that can be both a child and a parent of
itself. If I want to model parent and child entities that have a
completely different set of attributes (one is a group of objects, the
other is the objects themselves) am I better of not using
NSTreeController and CoreData? One problem I have already run into is
that when you bind your entire OutlineView column to a
NSTreeController entity it wants the parents and children to all have
the same attributes.
