Upcoming Improvements

High Impact, High Feasibility

1. Vue $t Helper (Pinned Issue #3444, open 4+ years)

• Strong community demand for concise $fm, $fn, $fd helpers

Medium Impact, Strategic

2. MessageFormat 2.0 (Intl.MessageFormat Polyfill)

• TC39 proposal progressing. Being the reference polyfill for MF2 would be a major strategic win.

3. decimal.js Bundle Size in ecma402-abstract

• 127KB dependency flowing into every polyfill. Evaluate if a lighter approach (native BigInt, lazy loading) is possible.

4. Rust CLI: Vue/GTS Extraction

• TS CLI has extractors for Vue, Handlebars, GlimmerJS that the Rust CLI lacks. Full parity would let us deprecate the TS CLI.

5. Framework Integrations: Svelte, Solid

• Only React and Vue have first-party integrations. Lingui already supports Svelte. Thin wrappers around @formatjs/intl core would be straightforward.
