wp_dropdorn_pages problem

Problem with a wp_dropdorn_pages function.
If look at the description of the function, then it says that you can explicitly specify the value of ‘post_type’. But in reality it does not work. All the matter in the function ‘get_pages‘ inside ‘wp_dropdown_pages’. If it’s replaced to ‘get_posts’, it would be a little easier life for developers. Or create a similar function for any ‘post_type’
Thanks
