It allows to start a communication with zero ceremony, and make the server code as stateless as possible, not even caring to keep a connection, but rather marking the response with the same ID as the request had, and let the receiver sort it out.

The built-in routing, flow control, and congestion control? Like, the actual protocol on top of IP on top of Ethernet frames.
