I'd say let's wait at least until it lands in Debian

It's worth noting that you don't have to necessarily change anything in the build process. As long as you plan to not insert partitions in the middle, you can:
write the image to the card with parted, resize the root partition to whatever you want make a new partition If you want to have more than 4 partitions total, this works best with GPT partition table, but legacy msdos works too with a little more effort `fsck.ext4 -f /dev/foo` where foo is the root partition `resize2fs /dev/foo` after you have the machine booted, you can then mkfs the new partition [you could probably do it in advance of booting the system too] I do this regularly, b/c I typically only partition about 1/2 or 1/4 of the SD card to leave the rest for wear-leveling.
 
Are you trying to do this as a one-off or are you trying to do it for a dozen or more SBCs of the same type?
