 > Right, this new design changes a lot about the page, so the intention
 was to leave the existing CSS in place for a cycle for any plugins that
 might use the about classes in their own pages. We can remove this all in
 an early patch in 5.4, so folks have more time to update.

 Right. Makes sense.

 > ...and an ie-rtl file that I didn't know exists and looks like it hasn't
 been touched since before 4.8.

 Yeah, ie.css and ie-rtl.css are old old IE6-compat CSS! Was meant to make
 wp-admin "somewhat useful" in super old versions of IE. That was around...
 WP 3.5 I believe :) Don't think it makes anything work now, lets remove it
 at the beginning of 5.4 too.

 > Aside from the notice, do you know of any plugins that do this? I don't
 think there are any other places _to_ hook in to add content.

 Both `admin-header.php` and `admin-footer.php` are included on the About
 screens. Don't think there would be any "problematic" HTML in the footer
 but there are few hooks in `admin-header.php` that seem used by plugins,
 the "notice" hooks and `do_action( 'in_admin_header' )`. As these fire
 outside the sections can assume they are "safe". Still maybe worth a quick
 "all plugins code" search to see if a plugin isn't doing something weird,
 but such cases would probably have been reported by now for recent
 releases.
