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?
