"Guys we can't fix this ever. We added wards and prevented it, but it is a failure"
"Hey guys. We should have made it into instance from the start. Then this exploit from people buying multiple accounts with multiple FCs to purchase entire ward wouldn't have happened for 4.2. In fact, we shouldn't have made this happen from 2.0-2.1 to 2.3-4.1. This was indeed our fault. Really.
Now you will have to deal with no instances in housings ever again, with no equal satisfaction for everyone to have their own houses.
You are welcome.

Is how I read about housing system even past 4.2 from the devs.
