InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
It's not quite the same though, as there are different considerations when using a repository of things a unified group has decided should be included and built (or slightly modified existing) packages for and a repo where anyone can submit a package that will go through some level of vetting. In the end I still believe most this discussion is really about individuals and how much trust they apply towards different groups and sources and is not really about Linux or Windows in particular as much.
