We all share the internet. Introducing features that make the internet work faster in an open standards body seems like a pretty reasonable thing to do, to me.

Domain isolation is important for security on the web (think about the problems CORS solves) and domain isolation right now requires using multiple connections, which is not great for performance. To me, this is just aligning security and performance, so that you don't have to choose. > I don't see the point of adding to TLS 1.3 when the crypto scheme seems to be moving towards another protocol anyway The authors of QUIC followed the same principle as the authors of this draft, and borrowed the handshake from TLS 1.3: "For those familiar with the TLS protocol, QUIC replaces the TLS record layer with its own framing format, while keeping the same TLS handshake messages." These changes go straight into browsers (Chrome, Firefox, Safari) and servers (nginx, caddy, etc), so you're going to benefit from the performance gains whether you like it or not! https://blog.cloudflare.com/the-road-to-quic/ https://blog.cloudflare.com/the-road-to-quic/
