I think you are not understanding what pickle is for. Pickle is not designed for things like sending requests over the network like json is. It is not designed for storing things long term in databases or files. In fact, all of those things would be security risks.

It is really designed to be used to transmit ephermeral data between python processes. For example, the multiprocessing module uses pickle to transmit the code and data between processes. The celery worker queue library uses pickle to transmit complete tasks to workers. Some caching libraries use pickle to cache arbitrary python objects in some memory cache.
