To avoid this issue, I intentionally never overwrote the actual function, so it should be possible to remove the compatibility layer, and secondly the docstring for every compatibility function starts with a line indicating that it is in fact a compatibility function: [Compatibility function for =E2=80=98cdddr=E2=80=99, defined in Emacs 26.= 1] > That said, it's just so much more practical for package authors to have > these compat shim libraries.
