What the current evidence supports

Human editorial judgment · 2026-08-20

Adopt with guardrails

Why
This standardizes the exact web-interop surface the ecosystem already relies on across Workers/Deno/Node, is Ecma-adopted (ECMA-429), and reduces polyfill drift — but it is a minimum baseline with no published conformance suite, so portability beyond the listed interfaces still needs verification.
Next
Target the Minimum Common API surface for new shared worker/edge code (fetch, URL, Web Crypto, Streams) and avoid runtime-proprietary globals; keep a thin shim for anything outside the standardized set.
