I need only package info like https://popcon.debian.org/ but getting stats about Fedora hardware similar to https://store.steampowered.com/hwsurvey/ is interesting.
I can not find the source code for Smolt. The first point at https://fedoraproject.org/wiki/Smolt_retirement#Rationale is that Smalt is not maintained for more than 10 months, but census GitHub is 5 years old.
I am not a fan of rewrites. It seems to me that taking http://web.archive.org/web/20121029093725/http://www.smolts.org/static/stats... and then fixing that is way faster than writing everything from scratch.
I wish rationale above contained more technical details, because rewriting is always a step back until everything is implemented, and it would be interesting to know what were design limitation and why census design is better.
