No, there's no reason it should be for forms only. In fact there's a  
patch by gordon in the queue that adds both pre_render and  
post_render optional callbacks for any drupal_render()'able  
structure. It's a good patch. +1! ;-)


This patch also makes it possible to take full advantage of  
hook_elements() default properties when building non-form structures  
that will ultimately be passed through drupal_render().
