 Hi @jhned, thanks for creating this ticket!

 Would hooking the
 [https://developer.wordpress.org/reference/hooks/the_posts/ 'the_posts']
 filter suit your needs? The first parameter is the list of posts (or
 revisions in this case), and the second is the query object.

 I'm thinking something along the lines of this:
 {{{#!php
 <?php

 add_filter( 'the_posts', 'myprefix_skip_original_revision', 10, 2 );

 function myprefix_skip_original_revision( $revisions, $query ) {
     if ( 0 < $query->get( 'post_parent' ) && 'revision' === $query->get(
 'post_type' ) ) {
         array_shift( $revisions );
     }

     return $revisions;
 }

 }}}
