Why is CF7 now loading polyfill and

The following JS asset is being loading by CF7 now but it is not disabled with the recommended filters. Can you please clarify why they are loaded and if they can be dequeued?

wp-polyfill.min.js

add_filter( 'wpcf7_load_js', '__return_false' );
add_filter( 'wpcf7_load_css', '__return_false' );
