What the current evidence supports

Human editorial judgment · 2026-08-20

Low-friction candidate

Why
Fully standardized (W3C phase 4) and now shipping across all three major engines (Chrome 137, Firefox 139, Safari 27 beta) with ~1us overhead — a real, low-risk capability whose only gap is GA Safari coverage, easily handled with a fallback.
Next
Adopt for Chromium+Firefox targets now with an Asyncify (or feature-detect) fallback for stable Safari until Safari 27 ships GA; profile any hot suspend/resume loops.
