Mapping Nested Shortcodes in Visual Composer

Working with nested shortcode with visual composer is super easy. Here is sample

// Shortcode 
// source : https://wpbakery.atlassian.net/wiki/pages/viewpage.action?pageId=524362

if(!function_exists('carousel_content')){
    function carousel_content( $atts, $content = null ) {
       return '<div class="owl-carousel content-carousel content-slider">'.do_shortcode($content).'</div>';
    }
    add_shortcode('carousel_content', 'carousel_content');
}

if(!function_exists('single_carousel_content')) {
	function single_carousel_content( $atts, $content =  null) {
		extract(shortcode_atts(array(
			'title' => 'Flexible & Customizable',
			'description' => '',
			'url' => '',
			'img' => ''
		), $atts));
        
        $url = ($url=='||') ? '' : $url;
		$url = ps_build_link( $url );
		$a_link = $url['url'];
		$a_title = ($url['title'] == '') ? '' : 'title="'.$url['title'].'"';
		$a_target = ($url['target'] == '') ? '' : 'target="'.$url['target'].'"';
        $button = $a_link ? '<a class="btn btn-md btn-black" href="'.$a_link. '" '.$a_title.' '.$a_target.'>'.$url['title'].'</a>' : '';

        $image = wp_get_attachment_image_src( $img, 'full');
		$image_src = $image['0'];
        
        
        $output = '<div class="item">
                    <div class="container">
                        <div class="row">
                            <div class="col-md-6 mb-sm-30">
                                <img src="'.$image_src.'" alt="" />
                            </div>
                            <div class="col-md-5 col-md-offset-1">
                                <h3>'.$title.'</h3>
                                <div class="spacer-15"></div>
                                '.$description.'
                                <div class="spacer-15"></div>
                                '.$button.'
                            </div>
                        </div>
                    </div>
                </div>'; 
        
        return $output;
	}
	add_shortcode('single_carousel_content', 'single_carousel_content');		
}

How to add parent for all VC shortcodes (custom & default)?

Hi. How do I make use of tabs inside vc accordion.

"super easy"

I was looking for a solution of nested containers for WPBakery, like <div>s and I found this (which is not what I was looking for, because obviously you can not nest same element into itself in WPB and that's crazy limiting),
but still I have a question: why would you do this?
Why not just create one custom element that will include that wrapper inside and items in repeater (or how it's called)?
Does this solution have any pros comparing to what I wrote?
