There should be a data-only pickle serialization protocol (that won't serialize or deserialize code).

How much work would it be to create a pickle protocol that does not exec or eval code?

python/cpython//Lib/pickle.py: https://github.com/python/cpython/blob/main/Lib/pickle.py

python/cpython//Lib/pickletools.py: https://github.com/python/cpython/blob/main/Lib/pickletools....

A data-only pickle serialization protocol implementation would need to skip calls to self.save_global() in pickle._Pickler.save() if condition(pickle_protocol) here https://github.com/python/cpython/blob/main/Lib/pickle.py#L5... and #L585 , and also in the save_type() dispatch table at #L1123 .
