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.

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).

### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
These can be set with `--set profile=<profile>`.
For example, the `demo` profile offers a preset configuration to try out Istio in a test environment, with additional features enabled and lowered resource requirements.

For consistency, the same profiles are used across each chart, even if they do not impact a given chart.
