Let me elaborate. Static types have multiple issues:
* Their lifetime is not well defined.
* It is not obvious when they are ready to be used.
* They are not destroyed at exit.
* They are incompatible with subinterpreters: each interpreter should have its own copy of a type, rather than static types are shared by all interpreters which cause problems with reference counting (require GIL or atomic operation).
* They are causing issues with stable ABI (limited C API): PEP 384.
