However, that doesn't necessarily mean a PR to add a value will be accepted.
The `values.yaml` API is intended to maintain a *minimal core set of configuration* that most users will use.
For bespoke use cases, [Helm Chart Customization](https://istio.io/latest/docs/setup/additional-setup/customize-installation-helm/#advanced-helm-chart-customization) can be used

## PeerAuthentication and ztunnel

        * Is the default behavior altered?
        * Is this turned on by default?
        * How many users are affected by this change?

## Feature implementation

Release managers will continue to have a final say in what gets merged or not, unless directed by the TOC. See the next
section if the implementation is done, but a bug is being addressed.
