Comment:

 A theme that uses post thumbnails would force the user to always have a
 post thumbnail - or break layout. The proposed function would make that
 much easier for theme authors. The only other way currently is to add a
 pretty complicated callback to the
 [https://github.com/WordPress/WordPress/blob/4.0/wp-includes/meta.php#L466
 get_{$meta_type}_metadata] filter.

 Use case/Example:
 {{{
 if ( have_posts() ) {
     while ( have_posts() ) {
         the_posts();

         the_title();
         if ( has_post_thumbnail() ) {
             the_post_thumbnail();
         }
         else {
             wp_default_img();
         }
         the_content();
     }
 }
 }}}

 One of the side effects that I could see is that theme shops or
 marketplace authors would have less questions of the following sort by
 users

 > "I installed the theme. Why doesn't it look like the demo?"
