As per request from Brion on IRC to file a bug on this. It will be very useful to be able to know which accounts are unified and bots can be used to relay that info to Freenode IRC so that it can be watched by admins of different wikis and stewards alike and prior to accounts being unified automatically on creation, we have had problems of vandal accounts being created and unified to bigger wikis (http://toolserver.org/~kylu/comet/locked.php) because they were never caught in time since ca.php is a bit slow and the alternate tool (http://toolserver.org/~sql/sul_log.php?) on toolserver lags a lot. I believe Tim said its possible for this to be done. It will be great if this can become a reality soon :) ..
