Per Peter Cai: apps shouldn't expect a particular MTU for UDP and should do loss-based path MTU discovery; there's no per-flow load balancing for UDP; and QUIC isn't supported through UDP services (it can technically work, with a lot of caveats).

  • UDP page: rewrites the MTU section and summary bullet; drops the "assume 1300 bytes" guidance.
  • UDP page: adds short sections on per-flow load balancing and QUIC (including HTTP/3, and that edge QUIC support is on the roadmap with no timeline yet).
  • Services page: notes in the HTTP handler section that there's no HTTP/3 or QUIC support, not to add a udp service on port 443 for it, linking to the UDP page caveats.

Closes superfly/docs-tracking#382
