Comment (by ocean90):

 On second thought, you can use the `parse_site_query` to register a custom
 query var like so:
 {{{#!php
 <?php
 function add_custom_query_var_to_default_query_vars( $query ) {
         if ( ! empty( $query->query_vars['custom_query_var' ] ) ) {
                 $query->query_var_defaults = array_merge(
 $query->query_var_defaults, [ 'custom_query_var' => '' ] );
         }
 }
 add_action( 'parse_site_query', __NAMESPACE__ .
 '\add_custom_query_var_to_default_query_vars' );
 }}}
