Hi @micnncim. Thanks for your PR.

I'm waiting for a istio 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.

Should we avoid taking over 2-letter names for alpha APIs ? I'm not sure how k8s reacts if different products register short names,
and we may already have a problem with the k8s Gateways if they start registering short name.

At least the 'short name' should have a failsafe setting, I suspect install would fail if there is a conflict ( I'm more concerned of what will happen with gateways for this @howardjohn )

Not blocking this, just thinking out loud.

If there is a conflict k8s picks one of them to "win" when you type `kubectl get ef`. I am not sure how it picks, it seems `kubectl get gateway` always picks the k8s one. I opened an issue in k8s to make it give a warning on conflict.

Thank you for point out the issue.

I've checked the related issues and PRs (kubernetes/kubernetes#94860, kubernetes-sigs/gateway-api#426).

The best solution would be that k8s takes care of this issue like warning, right? Because we can't expect a conflict with other CRDs completely.

However, since it's not certain k8s will take care of it, would it be better to take more than 2 letter word like evf, efl? IMO, typing something like kubectl get envoyfilter every time would be annoying for some of the users.

I wonder if we should have a policy against adding short names to alpha apis? Seems like it could be done as part of moving an api to beta. Thoughts?

All our APIs are alpha now, there isn't any harm even conflict with other CRs, is there?

@micnncim: PR needs rebase.
