CentOS Stream 9 recently pushed golang v1.22 into its repositories which is problematic when used with controller-gen < v0.14.0 as noted in https://github.com/kubernetes-sigs/controller-tools/issues/888#issuecomment-2046073715.

@phlogistonjohn

Is there anything which blocks an update to contorller-gen v0.14.0 or higher?

[phlogistonjohn]

Time and effort alone AFAIK.
