It's built on top of WebTransport, which is also quite new. But yeah, we're also seeing the input lag issue here and we're on it, will be fixed soon!

When it comes to loading resources ahead of time: this is something devs can choose per-game (i.e. show loading screen or not), but yeah you might be right that it would be better for the examples we have to show a loading screen instead.

It seems like the latency is due to all the games being coded to only enact state change upon server message (à la League of Legends aka "no netcode at all")

Since it would be up to the individual gamedev to implement their own client prediction, I don't think you can really "fix" the lag issue on a platform level unless you provide a system for automatic prediction and synchronization of arbitrary user-coded behavior, like Overwatch's StateScript framework: https://www.youtube.com/watch?v=5jP0z7Atww4
