Possibly.  The majority of the firmware is needed by the drivers.  If
those drivers aren't in kernel-core, the pre isn't needed on
kernel-core.  It would remain on kernel and possibly be added to

Aside from that (or in combination with it), it would basically be
splitting up linux-firmware into more subpackages or maybe putting
requires on specific files.
