One issue that springs to mind is that IIRC to make one certain
architecture's CDs bootable, the Debian CD scripts actually execute a "dd

- People like to check the images' md5sum, either to verify it was
downloaded correctly, or for security reasons.
- Other DDs who are concerned with certain aspects of the CD generation
process won't be too excited about any problems introduced by slightly
different CD images. With jigdo, I'm in the nice position of being able to
blame other people if e.g. CDs don't boot. ;)

Isn't support for signed .debs already implemented in recent dpkg versions?

You should also be aware that your solution won't be very popular if it
requires people to permanently dedicate several GB of disc space to a
partial Debian mirror. With jigdo, people can just toss their old CDs to
the program and say "reuse any files from these old CDs which also appear
on the new ones".
