It's probably this code?  But it works for me; it just sets up a symlink
from /tmp for compatibility with older emacsclients, I think?

(defun server-ensure-safe-dir (dir)

[...]

    (let ((olddir (or (getenv "TMPDIR") "/tmp")))
      (when (and (equal dir (format "%s/emacs" (getenv "XDG_RUNTIME_DIR")))
                 (file-writable-p olddir))
        (let ((link (format "%s/emacs%d" olddir (user-uid))))
          (unless (file-directory-p link)
            ;; We're using the new location, so try and setup a symlink from
            ;; the old location, in case we want to use an old emacsclient.
            ;; FIXME: Check that it's safe to use!
            (make-symbolic-link dir link t)))))
