I agree, but I think if we do that it would be highly desirable do
something to make the format discoverable.  For example, at the
beginning of each file and whenever the format changes, we write some
kind of unmistakable header line into the file identifying what fields
will be present on each line thereafter.  It's undesirable for log
analysis tools to need to contain logic that tries (imperfectly, no
doubt) to reverse-engineer the field list.
