You're worrying about issues that are rare in
practice, which was precisely my point. New
formats are rare enough that they can be handled
by manual intervention. And generally a new
format does indicate something important that
should be looked at by a person.
However, the vast majority of messages are not
new formats. They're the same old formats you've
seen before, and they can be recognized and
If manual intervention were required for every
message, this approach wouldn't scale or work. In
practice, manual intervention isn't required all
that often after the system is initially
developed and deployed.
