Additionally, we MUST accept incoming traffic during this time, both new and existing.
Typically, it is rare to get new connections after shutdown has started - once shutdown is triggered the endpoint is marked `NotReady` and removed from load balancing consideration.
However, some applications do not utilize Service readiness (connecting directly to the pod, etc).
