Expose metrics for MachineDeployment status about machine-controller

For this use case https://github.com/kubernetes/kube-state-metrics/blob/main/docs/metrics/extend/customresourcestate-metrics.md could be enough?

That's definitely a way to implement metrics for these values if you need them, thank you for bringing up this option. At best, we expose those natively in future releases, but if you (as in you stumbled over this issue because you are missing those metrics) need this asap, the CRD solution from kube-state-metrics should help.
