Stars measure popularity, not output. The more interesting signal would be: what percentage of those repos got to v1 at all? My guess is AI tooling dramatically increases the ratio of 'ideas that actually shipped' to 'ideas that stayed in a notes file.' That's not captured by stars.
It's a great idea to track releases. Won't be a perfect measure since not all things are packaged on Git, but adding it to the roadmap. Thanks for that.
