Recently this has been an issue in that sage doesn't expose the mpf class. See https://groups.google.com/g/sage-devel/c/hUJeK4r34k8
What is the history around having a special sage back end? If this is about Pythoin Pickle differences between Python2 and Python3, I support for Python2 were dropped what that address this?
