 There may be investment creating a new API definition for AKS from the [Managed Kubernetes CAPI proposal](https://github.com/kubernetes-sigs/cluster-api/blob/main/docs/proposals/20220725-managed-kubernetes.md) at some point in the future.  If interested in this functionality, please file an issue on the CAPZ repository and come to the community group meeting to discuss.
