Critically, the CA must enforce that the ztunnel has permission to request that identity.
Requests for identities not running on the node are rejected.
This is critical to ensure that a compromised node does not compromise the entire mesh.

This CA enforcement is done by Istio's CA, and is a requirement for any alternative CAs integrating with Ztunnel.
