Comment (by tifosi):

 Alternative patch: 22355.2.patch. Turned locations array into associative.
 Manipulation of array in filters by key.

 Usage
 {{{#!php
 <?php
 add_filter( 'template_locations', function( $locations ) {
     unset( $locations['theme-compat'] );
     array_walk( $locations, function ( &$v, $k, $s ) { $v .= $s; },
 '/partials' );
     return $locations;
 }, 10, 1 );

 add_filter( 'template_locations', function( $locations ) {
     unset( $locations['theme-compat'] );
     $new_locat = [
         'template-partials'     => get_template_directory() . '/partials',
         'template-templates'    => get_template_directory() . '/templates'
     ];
     return array_merge( $new_locat, $locations );
 }, 10, 1 );

 add_filter( 'locate_template', function( $location, $template_names ) {
     if ( in_array( 'header.php', $template_names ) ) {
         $location = ( is_child_theme() ) ? get_stylesheet_directory() .
 '/header.php' : get_template_directory() . '/partials/header.php';
     }
     return $location;
 }, 10, 2 );

 }}}
