AsyncLocalStorage gains using scopes for cleaner context binding, stream/iter moves to stable API, and JSPI WebAssembly support lands in production.
Summary
Using scopes eliminate manual context tracking boilerplate in async code; stream iteration standardization reduces fragmentation across async iteration patterns. For AI workloads, better async context isolation improves observability in concurrent operations.

Implementation verdict
Using scopes replace manual AsyncLocalStorage.run() wrapping—try it immediately if you manage deep async call stacks. Stream iteration replaces custom async iterator polyfills. Requires Node 24.20+; production-ready for LTS workloads, but audit permission audit mode needs explicit opt-in testing.
