New description:

 As a follow-up to [56649], it would be good to introduce a filter that
 allows even easier conditional addition (or removal) of hooked blocks for
 a given anchor block and relative position.

 Something along the following lines:

 {{{#!php
 <?php
 function insert_shopping_cart_hooked_block( $hooked_blocks, $position,
 $anchor_block, $context ) {
         if ( 'after' === $position && 'core/navigation' === $anchor_block
 && /** $context is header template part **/ ) {
                 $hooked_blocks[] = 'mycommerce/shopping-cart';
         }
         return $hooked_blocks;
 }
 add_filter( 'hooked_block_types', 'insert_shopping_cart_hooked_block', 10,
 4 );
 }}}
