None other than continuing to support the existing application.

Now that I think about it, I could probably re-work the existing application that uses the parsing logic to instead just call the fru-device DBus API (removing the need to expose the parsing logic via shared library).  Does that seem better?

Any issue with support for multiple formats at the same time?
