It would be great to have HTTP/2 support on Railway's edge proxy. HTTP/2 offers significant performance benefits like multiplexing and header compression, and it's also required for gRPC to work properly.

It's currently a blocker for use cases that rely on gRPC — without HTTP/2, gRPC simply doesn’t work. We're also seeing degraded performance with Server-Sent Events (SSE); while SSE technically works over HTTP/1.1, lack of HTTP/2 makes it inefficient and unreliable under load.
