but but but, the ucode image actually contains stuff for multiple
things.. so I have to like rename it to match the actual cpu in the
machine?

That seems rather daft..

awk 'BEGIN { FS=":" } /family/ {fam=$2} /model[^ ]/ {mod=$2} /stepping/
{step=$2} END { printf "intel-ucode/%02x-%02x-%02x\n", fam, mod,
step }' /proc/cpuinfo

Will get me the right filename, but surely that's not user-friendly at
all...

So no, that's not an improvement over /dev/microcode
