I'm unclear on the advantages of using one format over the other,
but one question comes to mind: once this is in, we will probably
want to have OpenSBI packaged separately in distributions, the same
way it already happens for SeaBIOS, SLOF and edk2-based firmwares.

Will using either of the formats prevent that from happening?
