@dprotaso at first glance, this seems like it overlaps with https://github.com/kubernetes-sigs/gateway-api/pull/2669, can you clarify if/how it's different?

That linked test is 'Extended' - we don't have a 'Core' test for the functionality I quoted from the spec

I was looking for a 'core' test that:

1. Doesn't specify a hostname in the Gateway
2. Has unique hostnames names in the HTTPRoute
3. Requests succeed for hostnames defined in the HTTPRoute
4. Requests fail for hostnames not defined in the HTTPRoute
