Ah, I see, so you really want to export the whole of
`package--builtin-versions` rather than just the list of builtin
packages.  This way you can later test for specific packages and/or
versions without running Emacs (modulo compatibility between Emacs's
notion of ordering between versions and that of what your external tool
uses).
