HTTP3 + QUIC support?

[NullVoxPopuli]

I've seen #1237

but now http3 is a thing, and I'd like to use http3 with proxies, too 🎉

We'll need

• HTTP/3 support nodejs/node#38478
  • Update on QUIC nodejs/node#57281
    per this comment

    As per comment in related PR quic: start re-enabling and working on quic with openssl 3.5 nodejs/node#59249 (comment), the goal is to have QUIC ready to go in time for the 25.0.0 release in October 2025.
