We haven't included Intel GPU firmware in the past as its use is not recommended - in fact, loading the Intel GPU firmware is disabled by default in the kernel (disabled by Intel) and needs to be enabled manually with a kernel command line option. Since firmware loading is not enabled by default (or recommended) it's just a waste of space - 8MB to be precise.

There was a brief time when it was enabled automatically but this change was swiftly reverted due to bugs. It's still disabled by default to this day.

If you want to test it yourself you can download the firmware files to /storage/.config/firmware/i915. Enable GPU firmware loading by appending i915.enable_guc=2 to /flash/syslinux.cfg and then you should see the following extra entries in dmesg (tested on a Skylake system):

text:
[ 0.052147] Setting dangerous option i915.enable_guc - tainting kernel

...

[ 1.105283] i915 0000:00:02.0: GuC firmware i915/skl_guc_33.0.0.bin version 33.0 submission:disabled

[ 1.105286] i915 0000:00:02.0: HuC firmware i915/skl_huc_2.0.0.bin version 2.0 authenticated:yes

More details here.

If/when Intel GPU firmware support is enabled by default then we will add the firmware to the image. 

Thanks @Milhouse
I'm runnning i915 FW enabled on an Skylake (Intel HD Graphics 530 (GT2) Gen 9) on an Fedora Desktop with vanilla kernels (since 5.4) without bugs.
