EA tried with the IFF (Interchange File Format) specification.  If you
have a file generated with version 4 of $app, and then load it in to
version 2 of $app, version 2 should be able to do what it does w/o
mucking up the data for version 4.  In theory.

I personally prefer extensible file formats.  I *want* to be able to
take the latest-and-greatest data file for $APP and load it in to an
older version of $APP.  This means, of course, that a LOT more thought
has to go into designing the file format ahead of time.

And if you could manage that transparently, someone would wonder why you
couldn't load your xfree config file into mpg123 and have it "just work..."

Simple is good.
