Yes. Packages which hide to-be-protected files in a let-form cannot
expect that we identify such files, except inside that let-form. This
isn't worse than today.

But we will protect users who do in their init file

(setq auth-sources '("~/.authinfo" "~/my-own-netrc-file-name"))

Maybe, additionally or instead of, all files with enabled reveal-mode in
the visiting buffer shall be protected as well. Another check function.

(defun reveal-mode-p (filename)
  (when-let ((buffer (get-file-buffer filename)))
    (buffer-local-value reveal-mode buffer)))

Best regards, Michael.
