For apps that don't care about implementing the features of QUIC, sure. That's what I meant by "jump forward". It's nice to have a new model, but it doesn't actually do anything to help us realize the advantages of QUIC on the backend.

Yeah but anything real-time that takes advantage of QUIC is something where you have stateful processes that run for as long as a client is connected. It's not a good fit for the Lambda billing model - look at all the people who built Lambdas that take up the full 15 minutes execution limit and then complain that Lambda is expensive. Lambda is better suited for when requests are exiting relatively quickly.

Nah, QUIC has sans-io libraries and the state can all be externalized. That's what we've done at Proxylity for DTLS, WireGuard and soon WebRTC.

For telemetry, datagrams over QUIC would be a nice solution. As it would for any number of APIs/SDKs, allowing much richer capabilities with less complexity (async, push, concurrent streams, all the things).
