I wanted the format to be reasonably generic, but yes, just for making
future extensions possible. I don't expect us to add anything beyond
the switchdev flag at this point. We don't have to implement the device
matching either. Just a comment in the code how we expect the full
format to look like would be enough, for whoever needs it in the future.
