>
> On the broker, the `BrokerMetadataPublisher` is responsible for propagating
> quota changes from `ClientQuota` records to `ClientQuotaManager`. On the
> controller, there is no similar logic, so no client quotas are enforced on
> the controller.
> On the broker side, there is no enforcement as well since the broker assumes
> that the controller will be the one to do it. Basically it looks at the
> throttle time returned in the response from the controller. If it is 0, then
> the response is sent immediately without any throttling.
> So the consequence of both of these issues is that controller-bound requests
> have no throttling today.
