No, and we're looking at splitting those out, but the fact is they are
a tiny amount of the overall firmware collection. You could even argue
either way for something like bluetooth due to it sometimes being used
by keyboards.

We actually already strip a lot of those in lorax. 

then, in cleanup, we wipe a bunch of files that have not yet been split
out from linux-firmware but which we know the installer env doesn't
need:

Thanks for the links. Putting aside the installer image... the firmware files mentioned in last link are not so small:

This is about 20 % of size of linux-firmware package. Can this be moved to to separate subpackage?
