Review comment:
This is something I had not considered. This also makes me wonder if
stateRequestHandlers can actually be scoped to the operator, or if they need to
be scoped to the bundle (which seems to have the lifetime of a partition, not
an operator). At any rate, any partition-scoped resources should probably be
passed to `getBundle` by the StageBundleFactory.
