In https://k8s.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/, it is still said that

{{< note >}}
Although the Device Manager component of Kubernetes is a generally available feature,
the _device plugin API_ is not stable. For information on the device plugin API and
version compatibility, read [Device Plugin API versions](/docs/reference/node/device-plugin-api-versions/).
{{< /note >}}

Do we need to revise this?

I think we can remove this note, as it is stable now and the feature gate is removed.
WDYT? @carlory @tengqm

@Shubham82 The graduation of the API and the DeviceManager component is split, according to this discussion https://kubernetes.slack.com/archives/C0BP8PW9G/p1667481109075849.

The graduation of the API is tracking, see kubernetes/kubernetes#113587.

@tengqm @Shubham82 what do you think ?

{{< note >}}
Although the Device Manager component of Kubernetes was graduated in v1.26,
the _device plugin API_ is not stable. For information on the device plugin API and
version compatibility, read [Device Plugin API versions](/docs/reference/node/device-plugin-api-versions/).

[Shubham82]

@carlory can we mention the issue k8s/k8s #113587 here, for better understanding of readers i.e. we Device Plugin API didn't graduate alongside the DeviceManager.
