Comment:

 Seems like this could be a common-sense enhancement for the featured image
 metabox -- especially if you take it in the same vein as #11157 where a
 `description` argument was added to `register_sidebar()`.

 That said, this seems quite edge-case, as, unlike sidebars, there's only
 one featured image metabox. Also, it's currently possible to simply inject
 your own description by prepending content via the
 `admin_post_thumbnail_html` filter.
