It's not like Safari are leading with this feature and others are catching up. With this particular feature, that's exactly what's happening. It's not the first time Apple shipped a new web platform feature before Google and Mozilla; it's the fact that it's been the most highly anticipated CSS feature in the recent history of the web platform. Leading implies followers. Apple shipped :has() December 2021 in Safari Technology Preview 137; it's been shipping in production since March 14, 2022 with Safari 15.4. That's a big gap in web time before Chrome ships in production.
