Removing X-UA-Compatible meta tag so pages validate

In preparing my first Aurora site for release I discovered the pages failed validation due to the annoying X-UA-Compatible tag for IE/Chrome Frame that isn't considered standard as of yet.

I researched this and found that you can work around the validation issue by using an http header instead of a meta tag. I quick grep showed that the html5_tools module is already doing this:

  // Line 222 of html5_tools.module
  if (variable_get('html5_tools_add_chrome_frame_header', 1)) {
    drupal_add_http_header('X-UA-Compatible', 'IE=Edge,chrome=1');
  }
 

I ended up adding this to my template.php to remove the meta tag Aurora is adding:

/**
 * Override or insert head content on the site.
 *
 * @param $head_elements
 *   An array of all head elements being presented on the page.
 */
function theme_html_head_alter(&$head_elements) {
  unset($head_elements['x-ua-compatible']);
}
// */

Would it make sense to patch Aurora to set the header instead of the meta tag and/or make this a theme option?
