On a few projects, I've discovered how ancient some software is (like, last commit more than 15 years ago ancient). Unless I missed something, `apt-cache show` doesn't show the upstream release date.
Naively, it seems feasible to add such a field, which front-ends like Synaptic can also display. Yes, I can click through https://packages.debian.org/ to find the link to the upstream code base and then pick through whatever interface the repo has to find out when they released whatever software version I'm using. But Debian could also include it. I think the usefulness of this feature is self-evident, especially when deciding which package from several options to install. Version numbers don't really tell much, unless they use increasingly fashionable date versioning. If two packages, superficially, do the same thing, I'll probably want the newer package. Alternatively, if I'm trying to stick to the most heavily tested software, I'll probably want an older package. If I want a package that supports technology that came out 10 years ago, using 15-year-old software probably isn't going to cut it. Aside from the "If you want it so much, you implement it and submit a PR," objections, what do people think of this?
