Comment 4 for bug 1977865

Hi, I've had a look into this on Juju 3.0 and have been able to replicate it.

I believe as well I have managed to diagnose the root cause of this as well. When Juju deploys metacontroller-operator, it creates the usual `metacontroller-operator` stateful set for the application

The charm's install hook then uses lightkube to create another stateful set `metacontroller-operator-charm` itself which Juju cannot track.

The charm's remove hook is then a no-op when it should clean up it's resources (hence the NotImplementedError I'd guess), hence the statefulset is left behind.

I believe is a bug with the charm, not with Juju
