I think this then mandates a PEP; I'm -1 on the feature also.

In the PEP, you should explain what the alternatives are and why
they don't work in the use cases of this feature. For example,
I wonder why just changing the classes to have the updated methods
isn't good enough. Or, if you want to be able to change the class
of all instances of that class, why you can't track all instances
explicitly.

In the PEP, you should then also explain what the limitations of
the feature should. I.e. the feature should not be specified by
its implementation, but have some abstract specification.
