Your call. I'm not completely sure when we should change it: setting it to nil will mean that pretty much any file compiled with the new Emacs won't run on older Emacsen. I think I'd like to see 24.4 release before making the change. But please do set it in your .emacs ASAP so it gets wider testing. Stefan
