Particularly nice as it saves an average of .5 mb.

Assuming debian-cd does switch to xorriso, so after it supports jidgo;
yes, I think this would be helpful. And we could use it in d-i's own iso
generation earlier.

I would caution that my idea of adding a partition for firmware is
potentially half-baked. Especially since it's only easily accessible
when using a USB stick, not when using a CD. The same problem could be
solved more generally by eg, using multisession to append the firmware
to the iso. But that would require the user run a script; the firmware
parition does allow even a user limited to Windows and no extra programs
to add firmware to their USB stick.
