> means that Safari can lag by three years in terms of features (case in point: WebRTC). In the case of WebRTC, it's even worse than that: public stable releases of Firefox and Chrome supported WebRTC by early 2013, but Safari took until late 2017. That's more than five years for an extremely popular feature (I had three professional engagements where we had to integrate a native WebRTC client component into a Cordova application, and couldn't support that feature on iOS through the browser, before they finally released it).
