KUDO Operator Framework Limitations?

[AndreArnesson]

If I refer to the operator maturity model https://sdk.operatorframework.io/docs/overview/operator-capabilities/, can an operator implement in KUDO really achieve full auto pilot? I'm thinking since the operator are developed declaratively using YAML. Other frameworks where you use a traditional programming language my understanding is that it is possible to achieve auto pilot.
What are the limitations compared to other operator frameworks?
Sorry for perhaps the weird question, it is university related.
