During startup this hook runs before the init file is loaded.  It is
called by this snippet from startup.el:

  ;; Under X, create the X frame and delete the terminal frame.
  (unless (daemonp)
    (if (or noninteractive emacs-basic-display)
        (setq menu-bar-mode nil
              tool-bar-mode nil
              no-blinking-cursor t))
    (frame-initialize))

It's not entirely a no-op, since there's early-init-file and
package-initialize, both of which are called before this hook.
