Enable development modules after syncing from @live to @dev

I threw together a post-sync hook to enable my development modules after sql-sync -- something I've been planning on doing for 1+ years now, maybe? My plan was to put it in Drush extras, or maybe an example in drush.api.php, but then I wondered if folks might want this in Drush core, as a standard feature of core-rsync? Could be generally useful.

Usage:

$aliases['dev'] = array (
  'root' => '/srv/www/drupal',
  'uri' => 'site.com',
  'target-command-specific' => array(
    'sql-sync' => array(
      'enable' => array('devel', 'hacked'),
    ),
  ),
);

Here's the hook; it could easily be moved to sync.sql.inc, if desired.

function sync_extras_drush_help_alter(&$command) {
  if ($command['command'] == 'sql-sync') {
    $command['options']['enable'] = "Enable the specified modules in the target database after the sync operation has completed.";
  }
}

function drush_sync_extras_post_sql_sync($source = NULL, $destination = NULL) {
  $modules_to_enable = drush_get_option_list('enable');
  if (!empty($modules_to_enable)) {
    drush_log(dt("Enable !modules post-sql-sync", array('!modules' => implode(',', $modules_to_enable))), 'ok');
    drush_invoke_process($destination, 'pm-enable', $modules_to_enable, array('yes' => TRUE));
  }
}
