Nixpkgs has 11k open PRs at the moment (a lot of them routine version bumps and such), so no. But then Nixpkgs isn’t a piece of software in the conventional sense: the monorepo does contain a few of those, but most of it is a giant collection of basically-independent build scripts.
that's the interesting part : forges are being abused.
Sure AI workflows might be a non-negligible share of all that usage but still the point is that initially forges existed to help developers collectively share a state then solve problems. Nowadays they are basically online filesystems with better notifications for other software to interact with and only optionally developers actually communicating.
