Native HTML form validation needed (back)

Hi, I need forms to be usable (and validate) without JS.

Since wpcf7_form_novalidate was removed in CF7 version 5.7 – would you be willing to either bring it back, or implement an alternative (perhaps something in Additional Settings)? Or is there an alternative, already?

It used to be simple enough:

add_filter(
  'wpcf7_form_novalidate',
  function( $support_html5 ) {
    return null;
  }
);

Now, it feels a lot more hacky 😉

add_filter(
  'the_content',
  function ( $content ) {
    return preg_replace( '/(<form .*class="wpcf7-form.*) novalidate="novalidate"(.*>)/isU', '\1\2', $content );
  },
  PHP_INT_MAX
);

Thanks for CF7!
