This would be more convincing if there were a simple stat on the home page of the dispositions of the reported bugs (fixed/no-repro/won't-fix).
As a random sample of one, I looked at one of the bugs this reported on Tailscale (first thing on the homepage) [0], and the pull request ends with "Apologies for the lack of due diligence here. I'll go ahead and close this out."
We should publish some stats. The fix rates on bugs are around 45% baseline, increasing over time as we learn from behavior within a given codebase. The merge rates for the codebase health work we do (e.g. deleting dead code) are very high, at least 90%.
