Comment:

 The [https://make.wordpress.org/core/2022/01/07/theme-focused-changes-and-
 filters-in-wordpress-5-9/#removing-the-icon-and-its-link dev note from
 WP5.9] probably could be updated. Here's a draft for the modified example
 and revision note:

 > `add_filter( 'rss_widget_feed_link', '__return_empty_string' );`
 >
 > For Twenty Twenty-One, the `after_setup_theme` action contains the
 filter. **''Update:''** Since March 2023, Twenty Twenty-One's filter
 returns an empty string instead of the boolean `false`. See #57594.
