 In [https://core.trac.wordpress.org/browser/tags/5.5.1/src/wp-
 admin/includes/class-wp-list-table.php#L583
 WP_List_Table::months_dropdown()], a query is run to determine the months
 that have post items.

 This query can be expensive for large posts/custom posts listing, so it
 may be desirable for sites to override this behavior. I am monitoring
 around 500ms for 500k+ posts.

 The filter available, disable_months_dropdown, only allows removing the
 dropdown not overriding the query.

 A [https://core.trac.wordpress.org/browser/tags/5.5.1/src/wp-
 includes/media.php#L4106 similar filter (media_library_months_with_files)]
 has been set previously for the media library. I was expecting a similar
 behavior for the month dropdown on post listing pages
