Hi @nauticalmike. 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

I don't think we should merge this doc for 1.22, as it doesn't work for waypoint. Might be working for 1.21 but for 1.22, sidecars aren't aware of waypoints thus this won't work.

Again this was decided by TOC to be out of scope for 1.22 - I'd recommend us focus on must items for 1.22 first for the remaining 2 weeks before 1.22 ships.
