**patchClassicComponent**

Set this option to `false` to prevent automatic `Component.reopen()` call which injects
the autogenerated class into component's `classNames` property.

You would need to use {{this.styleNamespace}} in *all* of your templates instead:

```hbs
<div class="wrapper {{this.styleNamespace}}">
Content goes here.
</div>
```

This is required to use `ember-component-css` with Ember 4+ since `Component.reopen()` was removed from Ember.js codebase.
For more details you may refer to [deprecation page](https://deprecations.emberjs.com/v3.x#toc_ember-component-reopen).
