I think "this" is something like the following.

;; Return the name of the init file directory for Emacs, assuming
;; XDG-DIR is the XDG location and USER-NAME is the user name.  If
;; USER-NAME is nil or "", use the current user.  Prefer the XDG
;; location only if the .emacs.d location does not exist.
(defun startup--xdg-or-homedot (xdg-dir user-name)
  (let ((emacs-d-dir (concat "~" user-name
                             (if (eq system-type 'ms-dos)
     ((or (file-exists-p emacs-d-dir)
          (if (eq system-type 'windows-nt)
              (if (file-directory-p (concat "~" user-name))
                  (directory-files (concat "~" user-name) nil
            (file-exists-p (concat "~" init-file-user
                                   (if (eq system-type 'ms-dos)
     ((file-exists-p xdg-dir)
     (t emacs-d-dir))))

This requires an etc/NEWS update as well.

I have no objection to symlinking, but Eli really wants to only use
XDG if .emacs.d is non-existent.
