I would change the example listed in the body of the PR so that it looks like the below. No need to list all of the parameters as they are not changing, the only thing that is changing is the name of the component :

Click for example:

       OLD
       {% from "components/onsMetadata/_macro.njk" import onsMetadata %}

       {{-
           onsMetadata({ ... })
       }}

       NEW
       {% from "components/description-list/_macro.njk" import onsDescriptionList %}
        
        {{
           onsDescriptionList({ ... })
        }}
