Lazy observation would completely remove the need for using weak references, simplifying the logic and making the whole system much easier to reason about.

While I agree that lazy observation would be a good improvement, it just shifts the problem one indirection away. You could still have an entire object graph that is needlessly kept alive by the property wrapper, which is a problem.
