Comment (by westonruter):

 @georgestephanis here's what I have in mind for adding restrictive
 filtering for `custom_css` settings for underprivileged users (who lack
 `unfiltered_html`). The following gives the essential logic for what I
 think Jetpack could do:

 {{{#!php
 <?php
 add_action( 'customize_register', function( WP_Customize_Manager
 $wp_customize ) {
         $sanitize_css = function( $css ) {
                 if ( ! current_user_can( 'unfiltered_html' ) ) {
                         $css = jetpack_sanitize_custom_css( $css );
                 }
                 return $css;
         };

         foreach ( $wp_customize->settings() as $setting ) {
                 if ( $setting instanceof WP_Customize_Custom_CSS_Setting )
 {
                         add_filter( "customize_sanitize_{$setting->id}",
 $sanitize_css, 10, 2 );
                 }
         }
 }, 20 );
 }}}
