Hi @rh-roman. Thanks for your PR.

I'm waiting for a openshift 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.

@rh-roman What's the motivation behind this PR? There's no description nor link to an appropriate jira card?

[kevinrizza]

@JoelSpeed We have been having a discussion about https://issues.redhat.com/browse/OCPSTRAT-2467, where the relevant reasoning is written in the description. We are starting by pulling all of these changes behind tech preview, which is what this PR is for. If it helps, we can discuss offline in more detail, but there's some significant asks from the business especially from HCM to pick this feature back to help with performance related to large LIST requests in managed clusters

[JoelSpeed]

@kevinrizza I've already been filled on on the strat, didn't make the connection that this PR was relevant/related to it.

Are we likely to be creating appropriate bugs to link to PRs for each of the required backports? This change looks fine, but there's admin to do

From a hygiene and future archeology perspective, I would expect the PR description to be included with appropriate detail please
