They should be in the changes file so they are uploaded together with it to the
archive (and so dak can process them). Not saying that should be mentioned in
policy though :)

Having them in the Binary section in the .dsc and Binary and Description in the
.changes files would mean modifying dpkg-buildpackage/dpkg-genchanges for ddebs
not listed in debian/control. However listing them in Files and Checksum-* in
the .changes requires no changes if you add the files to debian/files and use

Agreed. As per my previous paragraph, having them in Files and Checksum-* would
solve this.
