cache_javascript_headers() is not call by core

[pbearne]

I can't where this function is used in core should we move it to depicted if its not being used?

Historical uses, unused since WP 2.5 (This is a grep over ​https://core.svn.wordpress.org/branches/)

./2.3/wp-includes/js/tinymce/tiny_mce_config.php:	cache_javascript_headers();

./2.2/wp-includes/js/tinymce/tiny_mce_config.php:	cache_javascript_headers();

./2.1/wp-includes/js/list-manipulation-js.php:<?php @require_once('../../wp-config.php'); cache_javascript_headers(); ?>
./2.1/wp-includes/js/wp-ajax-js.php:<?php @require_once('../../wp-config.php'); cache_javascript_headers(); ?>
./2.1/wp-includes/js/autosave-js.php:cache_javascript_headers();
./2.1/wp-includes/js/tinymce/tiny_mce_config.php:	cache_javascript_headers();
./2.1/wp-admin/cat-js.php:cache_javascript_headers();
./2.1/wp-admin/dbx-admin-key-js.php:cache_javascript_headers();
./2.1/wp-admin/upload-js.php:<?php require_once('admin.php'); cache_javascript_headers(); ?>

According to ​https://wpdirectory.net/ it's used ​in a handful of plugins but nothing significant.

Seems like an ideal function to be deprecated.
