The activator is multi-tenant so it handles scale to zero for numerous Knative Services.

Activators sorta 'scale' out horizontally. Ideally we don't want them all to handle traffic for all revisions so we select a few activators (potentially of many) to act as the 'shield' for revisions.

I'm wondering if you're referring to the number of containers that are in the Pod that Knative creates. We have our own sidecar the queue-proxy that's there to enforce the concurrency limits you set. It also tries to manage the shutdown of the Pod gracefully by making sure traffic is drained.
