And that is exactly the reason why, the _pickle module doesn't use
__new__ for initialization.  Doing any kind of argument parsing in
__new__ prevents subclasses from customizing the arguments for their
__init__.

Although, I agree that __new__ should be used, whenever it is
possible, to initialize struct members.
