Does community edition connect-overload-protection exist?

Is it true that connection throttling, specifically the:

configuration defined here: https://docs.hivemq.com/hivemq/3.4/user-guide/restrictions.html#throttle-connection-rates is limited only to the Enterprise version?

If so, I’m expecting to use haproxy or nginx as a sidecar to implement this capability, but would like to avoid that if possible.

Answering my own question before closing, the feature comparison chart on the pricing page https://www.hivemq.com/pricing/self-managed/ indicates my suspicion, that this is an enterprise only feature.
