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

If the change is a dynamic runtime configuration, it probably belongs in the [MeshConfig API](https://github.com/istio/api/blob/master/mesh/v1alpha1/config.proto).
This allows configuration without re-installing or restarting deployments.

stable version in place and gradually migrate apps to the new version.

- More flexibility: the new installer allows multiple 'environments', allowing applications to select
a set of control plane settings and components. While the entire mesh respects the same APIs and config,
apps may target different 'environments' which contain different instances and variants of Istio.
