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.
