- Promote Immutable Secrets/ConfigMaps feature to Stable. This allows to set `immutable` field in Secret or ConfigMap object to mark their contents as immutable.

This is an inappropriate use of lazy types:

```groovy
class Example {
    Provider<String> getPath() {
        return project.provider(() -> path)
    }
}
```

Like above, this is an immutable part of the identity of the domain object and cannot be changed.
