That should work, but I forgot that you'd also need to remove the if from the plugin code, like:

$res = $vbulletin->db->query_first_slave("SELECT COUNT(*) AS count FROM " . TABLE_PREFIX . "subscribethread WHERE threadid = $thread[threadid]");
vB_Template::preRegister('SHOWTHREAD', array('subscribed_count' => $res['count']));
