I haven't really understood what problem this solves. Is this just a standardised form of documentation, or are you imagining that an automatic tool will use this to auto include a minimal set of firmware files in an initrd? I'm thinking of something like this: (1) redhat (or whoever) ships firmware files for every driver under the sun in /lib/firmware; (2) redhat wants to allow users to have a customized initrd with only essential drivers; (3) the tool goes through the list of essential drivers, looks up the firmware string via MODULE_FIRMWARE, finds the file in /lib/firmware, and includes it in the initrd.
All the best,
