Fix
All kernels need to support reading the compressed firmware files (even
after partial upgrades). See bug #2028550 for the kernel side.
linux-firmware needs two patches to correctly produce compressed
firmware files:

Fedora's individual binary firmware xz compression plans seem to be a
success. They kept going and divided the package into many different
