The mechanism it has now is effective only on fast machines.

                                                           Once you have

If and when such a mechanism is in place for us free software
activists, we might agree that open-paren-in-column-0-is-defun-start
is not worth while any more.  But it appears that has not happened
yet, so I think that the open-paren-in-column-0-is-defun-start guided
heuristic IS still worth while for us.
