 Currently sunrise.php is not included on multi-site file downloads as it
 is only called from /wp-includes/ms-settings.php, which is not included by
 /wp-includes/ms-files.php. Since mu-plugins and plugins are also skipped
 by SHORTINIT, there is no way to customize file downloading of which I am
 aware.

 Because the existing sunrise.php include capability isn't exactly aligned
 with this issue, a separate file to be included makes sense to me. The
 attached diff will include a WP_CONTENT_DIR . '/sunrise_ms_files.php' file
 if SUNRISE_MS_FILES is defined in wp-config.php.

 While my concern is securing file downloads for members-only sites (by
 including custom user-to-file authorization code), this fix could also
 allow for easily setting custom mime types. Example sunrise_ms_files.php
 content:

 {{{
 <?php
 add_filter('upload_mimes', 'add_custom_mime_types');
 function add_custom_mime_types($mimes = array()) {
         $mimes['abc'] = 'application/abracadabra';
         $mimes['def'] = 'application/defense';
         return $mimes;
 }
 ?>
 }}}

 #20136 and #14659 are related to the MIME type issue.
