 Since we have a filter for the function get_the_post_thumbnail:

 {{{#!php
 return apply_filters( 'post_thumbnail_html', $html, $post->ID,
 $post_thumbnail_id, $size, $attr )
 }}}

 should we also have a filter to the function get_the_post_thumbnail_url?

 I have a situation where I have made a plugin that allows setting a
 post_thumbnail image as an external url or similar so I am using the
 mentioned filter for displaying a custom post thumbnail.

 If a theme uses the function get_the_post_thumbnail_url, there is no way
 to return the custom url for the post thumbnail.

 Something like this could be helpful then:

 {{{#!php
 function get_the_post_thumbnail_url( $post = null, $size = 'post-
 thumbnail' ) {
         $post_thumbnail_id = get_post_thumbnail_id( $post );
         if ( ! $post_thumbnail_id ) {
                 return false;
         }
         return apply_filters( 'get_the_post_thumbnail_url',
 wp_get_attachment_image_url( $post_thumbnail_id, $size ), $post->ID );
 }
 }}}
