Yes, they need fixing.

But without firmware-in-module this would be akin to adding kernel 
module support in version 1.0.1, and forcing all distros to fix their 
stuff immediately in order to upgrade from version 1.0.0.

Permitting firmware-in-module means you do not force each distro, build 
script, and user immediately into the new regime, with the associated 
long list of breakage examples.

It's just sad because it feels "not the Linux way".

The way this was rolled out just feels "harder", far less friendly on 
the distros -- our customers -- than most other transitions.  Not as 
hard as vmlinuz->kmodule and IDE->libata transitions, I grant, but still 
  not the way we usually do things.

Nobody was ever objecting to request_firmware().  It was always about 
the removal of firmware-in-module and associated forced breakage on 
distros and build processes.  The fallout of _that_ is the rich source 
of breakage examples I've been pulling from.
