Being in the standard would change the question from "why" to "why not". I've used that feature when I worked with Oracle in a data warehouse situation. I found it most useful when migrating data dumps from mainframes where the data file contained subrecords and in cases where one field in a row changes the meaning of subsequent fields in the same row. That may sound like a First Normal Form violation, and it is, but such data formats are common in the IBM VSAM world, or at least they were in the data dumps that I had to import.
