Comment:

 I put together a quick POC of using the `get_header_image_tag` and
 `wp_filter_content_tags` callback to add the missing attributes. However,
 in my testing, it added async and lazy loading. Async is fine to add, but
 adding lazy this large header image does make a lot of sense. See screen.
