Comment (by toscho):

 These attributes are backwards compatible. I don’t think supporting them
 would do any harm.

 But I don’t like more arguments for `wp_register_script()`. We have
 already four, that’s more than enough. How about a very simple extra
 string in `WP_Scripts::do_item()`?

 {{{
 $src = esc_url( apply_filters( 'script_loader_src', $src, $handle ) );

 $extra = apply_filters( 'script_extra', '', $src, $handle );

 if ( $this->do_concat )
         $this->print_html .= "<script type='text/javascript' src='$src'
 $extra></script>\n";
 else
         echo "<script type='text/javascript' src='$src'
 $extra></script>\n";
 }}}
