This should probably be `final`, similarly to how
`initializeState(OperatorStateHandles)` is `final`.

> Partitionable operator and keyed state are currently only available by using
> backends. However, the serialization code for many operators is build around
> reading/writing their state to a stream for checkpointing. We want to provide
> partitionable states also through streams, so that migrating existing
> operators becomes more easy.
