At a mechanical level, when a feature is GA, kube removes the gating logic from code. Will we enforce this by preventing certain kubelet flags from being set?

yes we'll turn it off by setting the KubeletConfiguration NoSwap value, and also keeping the fail-swap-on flag on. CNV will be able to turn on LimitedSwap and turn off fail-swap-on

we have plans to provide API level gating of that in MCO KubeletConfig controller (which hopefully will detect the presence of CNV to toggle the gating off, details still need to be figured out)
