(With copy to Steve Purcell.) Steve Purcell has some code to do this, or at least parts of it, here: https://github.com/purcell/package-lint/tree/master/tools It comes out to this: https://github.com/purcell/package-lint/blob/master/data/stdlib-changes Perhaps Steve would be willing to contribute his work, or even help us integrate his tools into Emacs?
