Indeed.  And if there are any running processes.  This is I think the 
least surprising behavior for users who use the Emacs daemon.

I'm not sure I understand why this would be better.

If want you want is to save unsaved buffers and stop the daemon when you 
close the last frame, you can simply use:

(defun save-buffers-kill-terminal (&optional arg)
  (interactive "P")
  (if (and (frame-parameter nil 'client)
	   (cddr (frame-list)))
      (server-save-buffers-kill-terminal arg)
    (save-buffers-kill-emacs arg)))
