Mega Menu with no subcategories

Hi on our live site we often want to have CMS content in the drop down menu even when there is no sub category.

On line 268 of app/code/WeltPixel/NavigationLinks/Block/Html/Topmenu.php 

I commented out:

//if (!$child->hasChildren()) {
// return $html;
//}

We have content in weltpixel_mm_top_block and this does show up as I wanted. Could future versions support this ? Or is there more needed to be considered here or would this be a performance issue that it wants to return the $html instead of running the rest of the code ?

thanks
