## 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.

component of Ambient mesh.

## Issue management

We use GitHub to track all of our bugs and feature requests. Each issue we track has a variety of metadata:

eventually someone will want to customize every one of those fields.
If all fields are exposed in `values.yaml`, we end up with an massive API that is also likely worse than just using the Kubernetes API directly.

To avoid this, the project attempts to minimize additions to the `values.yaml` API where possible.
