Comment (by westonruter):

 @swissspidy Good catch! Patch amended.

 With this change, a plugin can do the (right thing) and use the GUID as
 the determination if the post actually already exists, using a plugin like
 this:

 {{{#!php
 <?php
 add_filter( 'wp_import_existing_post', function( $post_exists, $post ) {
         if ( $post_exists ) {
                 $existing_post = get_post( $post_exists );
                 if ( $existing_post->guid !== $post['guid'] ) {
                         $post_exists = 0;
                 }
         }
         return $post_exists;
 }, 10, 2 );
 }}}
