I did not mean to remove the existing mechanisms. Just wanted to allow additional check _before_ matching filename with a regexp. (And I demonstrated that such a check is generally faster compared to invoking regexp search) Also, note that `inhibit-file-name-handlers' could then be implemented without a need to match every single handler against `inhibit-file-name-handlers' list. Emacs could instead have handler-enabled-p flag that can be trivially let-bound. Checking a flag is much faster compared to (memq handler inhibit-file-name-handlers). Of course, the existing mechanism should be left for backward compatibility. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
