I think we also discussed it for when a new section was added that wasn't
known to the current trace-cmd, that it could give a more useful message.
i.e. "This version of trace-cmd does not handle 'New feature here', please
upgrade your trace-cmd". 

That way, the user would at least know why that new feature is not being
processed.
