The OpenTelemetry Maintainer Concentration Spreadsheet Hit the Hacker News Front Page, With Ruby at 78.7% Single-Maintainer Merges
Mat Duggan's audit of OpenTelemetry merge concentration reached 143 points on August 21, ten days after publication. The numbers: 78.7% of Ruby SDK merges come from one person, 61.4% for Python, 53% split across two people for PHP, against 36.9% for Go and 31.5% for .NET, while Prometheus sits at 14.4% across 31 distinct mergers. Since OTel is the vendor-neutral escape hatch every observability buyer cites when negotiating with Datadog or New Relic, per-language maintainer risk is a direct input to whether that leverage is real.
