Hi @alejandroEsc. 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.

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.

Discussed this in the Feb 23 2022 office hours. A recap:

ClusterResourceSet is experimental, and updating its functionality is part of its experimental nature. The project offers no API guarantees; CRS can be deprecated at any time.

However, because there may be enough time to implement a longer-term alternative to ClusterResourceSet before the next minor release, some maintiners would like additional time to consider the alternative, before merging this PR.

Until further discussions on the addons RFE #5491 and related proposals

[joejulian]

@vincepri I'm confused. We had discussed your desire to block this and there didn't seem to be any community consensus to do so. I don't see any reason to not let this move forward because CRS is experimental and changes to it have no bearing on the outcome of #5491.

@g-gaston Do you want to add anything? This affects your project as well, as I understand it.

closing as we are not considering this anymore
