That is disappointing.

I ended up manually dequeuing the problem script on the coupon and subscription admin pages like so:

add_action( 'wp_print_scripts', 'caldera_fix', 99 );
function caldera_fix() {
    global $current_screen;

    if ( wp_doing_ajax() ) return;

    if ( wp_script_is( 'caldera-forms-shortcode-insert-scripts', 'enqueued' ) && ( $current_screen->post_type === 'shop_coupon' || $current_screen->post_type === 'shop_subscription' ) ) {
        wp_dequeue_script( 'caldera-forms-shortcode-insert-scripts' );
    }
}
