I wonder if anyone could shed some light on this subject?
(Or, help me understand, what is the difference between a type that I create using python C api and a python class?)
This is prohibited intentionally to prevent accidental fatal changes to built-in types (fatal to parts of the code that you never though of). Also, it is done to prevent the changes to affect different interpreters residing in the address space, since built-in types (unlike user-defined classes) are shared between all such interpreters.
