It is rude to call our packages useless, it is unfriendly and unkind to those that work on them. Please don't do that. You might not have a usage for them, but the person who wrote it clearly found a use for it, including the GNU project that accepted that it is part of the GNU project.
Wether a package is to be decomissioned, or some how made obsolete is up to the package maintainer, and St. IGNUcius. It is not done based on what Debian includes.
