I think we should focus on getting things to work with realistic
blobs, i.e. such that distros and their tools would generate. If you
update a respective package, it'll be clear which blob is the latest,
and there's generally not going to be two blobs for the same family
put on a single system. People obtaining ucode blobs manually from
elsewhere should know what they're doing and not try to paste
together two of them targeting the same family.
