The modeline display is fully configurable.  You can, for instance,
first remove all of the existing mode line widgets from mode_line_hook.
Note that in modules/mode-line.js there are these three calls that are
responsible for the default mode line:

add_hook("mode_line_hook", mode_line_adder(current_buffer_name_widget));
add_hook("mode_line_hook", mode_line_adder(clock_widget));
add_hook("mode_line_hook", mode_line_adder(current_buffer_scroll_position_widget));

Unfortunately, due to the nature of mode_line_adder, it was previously
not possible to merely substitute remove_hook for add_hook to reverse
the action, because a new function closure would be generated by the
call to mode_line_adder, rather than exactly the same one generated in
the call to add_hook.  Thus, the only option would be to clear the hook,
e.g. by setting mode_line_hook.length = 0;  I pushed a fix, though, so that now you can
indeed call:

remove_hook("mode_line_hook", mode_line_adder(current_buffer_name_widget));
remove_hook("mode_line_hook", mode_line_adder(clock_widget));
remove_hook("mode_line_hook", mode_line_adder(current_buffer_scroll_position_widget));

To remove all of the default mode line widgets.
