Source: automake-1.17 Version: 1:1.17-1 Severity: minor src:automake-${version} source packages made sense back in the days when there were also several automake-${version} binary packages in the archive.
Today automake is stale and stable, and there will likely never again be more than one version in the archive. Today src:automake-${version} gets you a round through NEW for each new automake major release, and also means some bugs have to be moved manually from the old to the new package - with no benefits anymore of haveing the version in the source package name.
