As we talked I would like to graduate the CapacityBuffers to beta soon. To ensure that there is clarity about the graduation criteria I am adding a "timeline" to the CapacityBuffers proposal. |

I think this isn't broad enough to cover the usecases. Given that this API is a general autoscaling api, more than 1 autoscaler should have support for a couple months before we can graduate. At the minimum 1-2 OSS autoscalers like CAS or Karpenter should support the api.

Note that there is already 1 OSS implementation in CA OSS which was part of the alpha scope.

After some discussion on Slack with @ellistarn and other karpenter maintainers I am changing my proposal to include waiting for karpenter implementation up to some number of versions (to be discussed how many are needed). |
|
Removed e2e test implementation from beta graduation as all of the e2e tests are failing and I do not want to put fixing them on the path to beta. V1 should not happen without e2e tests and there should be enough time to fix them. |

So you'd target 1.37. While I fully expect us to come to a decision before then, I'd hope we could have a conversation rather than falling back to lazy consensus.

Isn't 1.35 more or less closed at this point? I thought it was launching very soon.
