Way to raise the default maxConnections

[dghubble]

I'm finding that the envoy proxy default of 1024 max connections is quite low. So every HTTPRoute is having to define a BackendTrafficPolicy to raise it. I've not found a way to raise the default and recently tried to bind a BackendTrafficPolicy to the gateway to provide a higher default.

apiVersion: gateway.envoyproxy.io/v1alpha1
kind: BackendTrafficPolicy
metadata:
  name: default
spec:
  targetRefs:
    - group: gateway.networking.k8s.io
      kind: Gateway
      name: mygateway
  circuitBreaker:
    # Envoy Proxy defaults to 1024 which is too low
    maxConnections: 30000

But with envoy-gateway 1.2.5, dumping the envoy proxy config shows its still using 1024 for an HTTPRoute that otherwise has no BackendTrafficPolicy.

Is this approach supposed to work (i.e. bug)? I know security policies have a most specific match behavior but I've not seen that claimed for BackendTrafficPolicy.

is there any error thats flagged in the status - kubernetes get btp/default -o yaml

there's also a test case that validates this use case
