[WooCommerce Subscriptions]: Give access to downloadable files even if Subscription is cancelled

woocommerce-subscriptions-download-access-after-cancelled.php

<?php

/* 
 * Access to downloadable files associated with a subscription will, by default, expire
 * when the subscription is no longer "active" or "pending-cancel". 
 * https://woocommerce.com/document/subscriptions/faq/#section-39
 * This snippet overrides that behavior to allow access as per the Download Expiry settng
 * when the subscription status is "cancelled" 
 */

add_filter ( 'woocommerce_order_is_download_permitted', 'wc_subscription_download_access_after_cancelled', 10, 2 );

function wc_subscription_download_access_after_cancelled( $is_download_permitted, $subscription ) {
  
  if ( $subscription->has_status ( 'cancelled' ) ) {
      return true;
  }
  
  return $is_download_permitted;
  
}

Could the permissions also be restricted to the length of the subscription billing period it originally to be?
