Disable Object Cache

I’d like to disable the object cache, as the file would still load even tho the plugin is not active.

In wp-includes/load.php the code looks like this:

if ( file_exists( WP_CONTENT_DIR . '/object-cache.php' ) ) {
	require_once ( WP_CONTENT_DIR . '/object-cache.php' );
	$_wp_using_ext_object_cache = true;
}

Therefore it will always include the object-cache.php file even tho we dont need it now.

An easy fix could be:

wp-includes/load.php

if ( file_exists( WP_CONTENT_DIR . '/object-cache.php' ) && WP_OBJECT_CACHE ) {
	require_once ( WP_CONTENT_DIR . '/object-cache.php' );
	$_wp_using_ext_object_cache = true;
}

wp-includes/default-constants.php

if ( !defined('WP_OBJECT_CACHE') )
	define('WP_OBJECT_CACHE', true);

Why is it currently not possible to disable object cache?
