## Proxy implementation

In its initial implementations, the ztunnel was actually implemented in 3 different ways: a bespoke Rust implementation, a bespoke Go implementation, and in Envoy.

In the end, [after evaluation](https://docs.google.com/document/d/1c2123cKuYsBDpIon9FFdctWTUIMFweSjgwG7r8l3818/edit), the decision was to move forward with a Rust implementation.

  // will pause until the driver deployment has published
  // some suitable CSIStorageCapacity object.
  //
  // Alternatively, the driver can be deployed with the field
  // unset or false and it can be flipped later when storage
  // capacity information has been published.
  //
  // This field was immutable in Kubernetes <= 1.22 and now is mutable.
