I was naturally wondering what some use cases of this would be. Anyone have ideas?

You could: - Stream-process JSONL. - Replace strings for translations while streaming. - Stream Video. I guess you don't mean WebSockets, since that has a myriad of use-cases, everything from chats, games, charts, feeds etc.

You could run trusted game server proxies. In FPS games this would help with the latency vs cheating trade-off. 1. An enemy is hiding behind a corner. The player takes a step and sees the enemy. If the client knew the enemy was there, the player could cheat. If the client didn't know, the player would see the enemy with a delay. The proxy can share the hidden state at exactly the right moment. 2. When the player thinks that their shot hit the target, but the central server disagrees. If the client is trusted to determine the answer, the player could cheat again. If the client isn't trusted, the player would sometimes see a hit that didn't harm the target. The proxy can make the decision and provide accurate feedback immediately.

  This seems like its http and web sockets, so probably not useful for game networking until HTTP/3 and WebTransport happens so that UDP becomes possible.

    If a game doesn't want TCP at all for whatever performance metrics they think they need to hit in their networking stack, HTTP/3 is not likely to meet their needs/standards/expectations either even over UDP because HTTP/3 just moves some of TCP's stack into the application protocol over top of UDP and in some ways remains "just" a TCP-over-UDP tunnel.

      Could you elaborate? I'm not sure I understand. The main issue that UDP solves in game networking is being able to send/receive out-of-order messages, which will be possible with WebTransport datagrams.

Streaming in particular can provide a huge performance boost for server-side rendered pages. In theory, server-sent events can also provide performance benefits (both in page weight and runtime) by moving more dynamic behavior from the client to the server.
