I heavily rely on ComponentAttributes instantiation in components to be able to use same logic on all component elements, for example:

```twig
<div{{ attributes.defaults({ ... })>
  <img{{ imageAttributes.defaults({ ... })>
</div>
```

In the issue it was proposed to rename ComponentAttributes but I don't see the point to break the code for people now 🙂
