I think there were a few:
1) Got rid of people just trying Graal, but creating accounts that they never returned to, thus creating a pile of inactive accounts. I think I'd rather just have them flush out inactive accounts, however.
2) Made back-door handling of account names easier. If someone requests an 'account name' change, they simply change the community name, and all other data stays intact. I don't think it was very easy to do this sort of thing before the community names.

Either way, I would love to have the old method back. I'm sure Stefan could figure out a way to convert the community accounts over to the old system.
