I think it's better to sign a package than individual files: - the package manager can do the verification at install time (once) - there's already a packaging process which can easily have the extra signing step, and packages have metadata we can use - signing a package would cover all the files, not just Emacs Lisp files, and would be done just once per package - the Emacs Lisp code doesn't have to be polluted by the signing info - older and legacy code doesn't have to be modified to be signed So I think it's good to have the support you mentioned but for package.el instead of at the Emacs Lisp code level.
