Comment (by JakePT):

 @Kenshino In map_meta_cap is seems fairly trivial to just set it to
 manage_options if the post in question is the front page or posts page:
 {{{#!php
 <?php
 case 'delete_page':
 ...
         if ( get_option( 'page_for_posts' ) == $post->ID ) {
                 $caps[] = 'manage_options';
                 break;
         }

         if ( get_option( 'page_on_front' ) == $post->ID ) {
                 $caps[] = 'manage_options';
                 break;
         }
 }}}
 But that doesn't provide any explanation to the user about why, and
 doesn't account for the ability to unpublish the pages by setting to
 draft, private etc.

 I'm not 100% sure that either are necessary, but worth considering I
 think.
