> 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.
