Hi @stevesloka. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

I'm struggling to get the docs to regen. My mac just won't get the right bits to work. Could we have an optional docker build step to run those in docker removing the need for local deps?

[robscott]

@stevesloka No need for docs generation at all anymore, we've moved to Netlify. Deploy previews are available from "deploy/preview" presubmit (this one is https://deploy-preview-572--kubernetes-sigs-gateway-api.netlify.app/).

w00t! Thanks @robscott! =)

Unfortunately k8s infra doesn't like fixes keywords in commit messages so this can't be merged until that is removed. (kubernetes/test-infra#9360)

[stevesloka]

Sorry, it's a habit @robscott. I updated the commit message to remove that.

[hbagdi]

Like #564, this is another case of an optional struct should be a pointer.
We discussed previously that we need to audit the entire code to ensure this is the case.
I think we should certainly do that but such small improvements are also good.
