We should probably follow https://gateway-api.sigs.k8s.io/guides/getting-started/ here:

• Simple Gateway
• HTTP Routing
• HTTP Redirects, but note that we think that rewrites aren't working yet
• HTTP Traffic Splitting
• Routing Across Namespaces
• TLS may not be supported
• TLS passthrough

Note that TCP Routing is not currently supported, and we should explicitly call that out.
