Let me try providing a different perspective based on experience. QUIC works amazingly well for _some_ kinds of machine to machine traffic.

ssh3, based on QUIC is quicker at dropping into a shell compared to ssh. The latency difference was clearly visible.

QUIC with the unreliable dgram extension is also a great way to implement port forwarding over ssh. Tunneling one reliable transport over another hides the packer losses in the upper layer.

The article that GP posted was specifically about throughput over a high speed connection inside a data center.

It was not about latency.

In my opinion, the lessons that one can draw from this article should not be applied for use cases that are not about maximum throughput inside a data center.
