First, I'll cheekily answer what you asked instead of what you meant to ask:
One of the important properties of post-mortem finalization is that it is *not* triggered by the collection of the weakref itself, and is not triggered if the weakref is co-condemned with the object it points at. On your real question, the answer is no. This might be appropriate as parts of the guts of some fancy debugger as you suggest. But as something generally available in the language, its cost would be prohibitive.
