In 2008 ubuntu had Sha256Sums wrong which showed that back then almost
not software even bothered to check those fields:
non-md5sum hashses in Sources generated by DAK were incomplete until
the generation code moved away from apt-ftparchive (early 2011 I think),
thus only the Files: part with md5sums was the only reliable way to get
the list of all files belonging to it.
Support for non-md5sum hashes was added to dpkg-scansources/apt-ftparchive
with apt (0.7.25.3) released to unstable 2010-02-01, first released with
So it is not some 8 years. It is more "since squeeze" that Debian and
some of the common tools even produce complete non-md5sum hashes in
reprepro for example only tries to support source indices without
"Files" (i.e. md5sum hashes) since 4.12.0 (i.e. since wheezy).
