Looking at the tempfile code more, I agree with Serhiy that changing it should be rejected. Python is a duck-typed language (essentially what Martin said). People should not be over-zealous in using instance checks.
The doc specifically says that TemporaryFile returns a *file-like object*
https://docs.python.org/3/glossary.html#term-file-like-object
which only require implementing the interface.
