I’d love to see these comments about Safari lagging give specific examples. Every time I’ve seen specifics, it’s either only interesting to progressive web apps, or blatantly user hostile tracking/nagging “features”. In my personal experience as a web dev, Safari is often the first to implement new features, and otherwise lags literally just a few months behind, according to their release cycle. WEBP was the exception that was both a real feature and very delayed, but now with JPEG XL it’s Safari first by a mile and Chrome holding everyone back.
