enable or disable JavaScript SDK

In many wordpress plugins is duplicated the JavaScript SDK

It’s possible to turn on or off the inclusion of this item in wppa-non-admin.php:

/* FACEBOOK COMMENTS */
function wppa_fbc_setup() {
	$wppa_app_id = '';
	$wppa_lang = get_locale();
	if ( ! $wppa_lang ) $wppa_lang = 'en_US';
	?>
<!-- Facebook Comments for WPPA+ -->
<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/<?php echo $wppa_lang; ?>/all.js#xfbml=1&appId=<?php echo $wppa_app_id; ?>";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>

in case the user has already loaded by another plugin?

I at the time I solved deleting it.
