Does community edition connect-overload-protection exist?

Is it true that connection throttling, specifically the:

configuration defined here: 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 indicates my suspicion, that this is an enterprise only feature.
