This is how I understood the the situation, but I never quite bought
it. What is wrong with the kernel saying "you must put your module and
your firmware together"? Sure, people may want to do things
differently, but what is the real blocker?

Fundamentally, it seems to me that if a module needs firmware, it
makes no sense to make the module available before the firmware. I'm
probably missing something though :)
