Route groups are reliable, ordered, head-of-line-blocked on packet loss — exactly the contract <code>net.Conn</code> callers expect. That&rsquo;s the right shape for HTTP, SSH, raw TCP forwarding, and almost everything else apps reach for by default.</p> <p>But real-world UDP applications — DNS, NTP, VoIP, gaming, QUIC, anything that has its own loss-tolerance built in — treat <strong>late packets as worse than lost packets</strong>. A DNS resolver that retries after 100ms doesn&rsquo;t want the original response to arrive 5 seconds later through a TCP-shaped tunnel. A VoIP codec that masks 20ms of lost audio doesn&rsquo;t want all subsequent audio to wait while the lost packet retransmits. A gaming engine doesn&rsquo;t want the world-state update from a frame ago — it wants the current update or nothing.</p>
