Today Ztunnel suffers from unbounded metric growth the same way istio-proxy did, originally tracked via istio/istio#21377 and resolved via istio/istio#44605.
This issue exists to track resolution for Ztunnel.
Current blocker appears to be pushback on Prometheus' rust client side (see prometheus/client_rust#197) but alternative approaches may exist.
This problem is particularly prevalent in situations where destination services are ephemeral/short-lived, driving memory growth in line with service creation.
