Yup... but before we go to far I think anyone who is thinking of adding
a column should see if there is a comparable column in
oracle/db2/$ql$erver.  The point of information_schema (at least one
point of it) is to help application writers to write code that works
across different database systems and I wouldn't be surprised if those
folks had already extended the information_schema in some way.
