3One source for API versions that more than one service calls through the 

4generic ``CustomObjectsApi`` (which takes the group and version as plain 

5strings, so nothing in the client library pins them). Standard library only: 

6every service image copies ``gco/`` wholesale, so anything imported here is 

7imported by every service.

16``metrics.k8s.io/v1`` is GA in Kubernetes 1.37, but the metrics-server 

17add-on GCO pins (``EKS_ADDON_METRICS_SERVER`` in ``gco/stacks/constants.py``, 

18a ``v0.9.x`` build) registers only ``v1beta1`` in its ``pkg/api/install.go``; 

19upstream ``master`` registers ``v1`` as well, so the first release to carry it 

20is expected to be ``v0.10.x``. Flip this to ``"v1"`` once the pinned add-on is 

21such a release (``tests/test_k8s_api_versions.py`` fails on a ``v0.10+`` pin 

22while this still says ``v1beta1``, as the reminder). The RBAC grants in 

23``lambda/kubectl-applier-simple/manifests/02-rbac.yaml`` name only the group, 

24so they need no change when the version moves.
