I think gaming netcode engineers would love to ditch CSP, but the problem is even though low-latency connections are mainstream, stable latency connections are not. It's always possible to have lag spikes or temporary slowdowns in your routing or connection. Second, it's also possible to end up through matchmaking lobbies on a server halfway around the world from one or more of the players in a given match. At some level the limitations of physics still result in noticeable latency and CSP is still mandatory for any fast-paced real-time online multiplayer game.
