Cisco SB switch processor info missing since r13097

A breaking change was introduced in r13097 that stripped the CPU metric off all cisco small business switches.  r13096 has CPU graphs still but once I upgrade to 13097 they disappear:

root@observium:/var/www/observium# svn up -r 13097

The issue appears to be the deleted file: 
includes/discovery/processors/ciscosb-rndmng.inc.php

I updated to the latest r13244 and copied ciscosb-rndmng.inc.php back in and CPU graphs are working again.  Any idea why this file was deleted?
