[Zope] DAMN Traceback!

what's the reason behind tracebacks being *allways* printed on zope? don't tell me to disable the debug mode, because that doesn't really remove the traceback from the output, it just html quotes it. why did ZC leave this behaviour as is ? wouldn't it be much more elegant if it could be handled by the standard_error_message or anything like it. I'd like only managers to see tracebacks, why should an untrusted user have access to such information? btw, I'm not looking for a patch, just an answer =) Thanks alex
