Shows a concrete path that turns @deprecated into governance and runtime tooling: add replacedBy/migrationURL and sunset date args, run a schema transformer that returns fields but adds extension warnings, log hits and errors for post-sunset requests, and capture client identity via GraphQL context so observability is client-aware telemetry. A registry plus agents then scan usage, open PRs to migrate or prune after ~2 weeks of inactivity, making deprecation actionable, automatable, and enforceable.
