Agreed, but that's not what is going on here at all.

This is the firmware that is in the kernel source tree, that has been
moved to use request_firmware, and was originally tied tightly to the
kernel drivers themselves.

Now I can't install multiple kernel versions of a rpm package on my
machine at once. Or even a single rpm package and then my own build,
without stomping on files owned by a different package.

That's unacceptable and can not work and is why Jeff made this patch.
