Committee process runs on staged proposals and concrete artifacts: stage 4 means two+ implementations and a shared test suite, stage 3 features have browser implementations and Babel/TypeScript support. Examples: dynamic import, optional chaining and nullish coalescing are shipping in engines and bundlers; WeakRef (weak graphs) and private #fields reach stage 3; decorators sit at stage 2; pipeline, records & tuples are stage 1 and BigDecimal is discussed at stage 0. Specification lives on GitHub, tests live in test suites, documentation, surveys and polyfills exist.
