[jQuery] Forms AjaxSubmit: no error handling?

Hey all,
In using the AjaxSubmit method of the Forms plugin, I notice that there is
no error param to allow for the handling of an server side error after
submission of the form.
How are people handling this? I was thinking about just using ajaxForm and
then doing the submit using the jquery $.ajax method, which does have error
handling? How are other people doing this?
