All reports of uses-no-compression-for-data-tarball for the archive. The extended description of this tag is:
The data portion of this binary package uses a non-compressed format. Although dpkg will support extracting such binary packages since dpkg 1.10.24, creating them is not advised except in special cases.
Except if data is non-compressible, use gzip for maximum compatibility and speed, and xz for maximum compression ratio.
Refer to the deb(5) manual page for details.
