Having the uncompressed files on the cdrom should not be needed, apt
should simply fetch the compressed ones if the uncompressed ones are
missing. It does need the hash of the uncompressed one in the Release
so that it can verify that it matches after the uncompression.

Having something stronger than gzip is certainly a good idea, apt
should deal just fine with .xz. If its easy for you then maybe we
could generate a netinst image with the above changes (plus switching
to .xz) and I can test against the current apt and fix (potential)
issue on my side. Alternatively if you could give me a quick hint how
to generate a netinst (or similar iso) I can try to generate a
testimage myself.
