This allows user accounts to end up without a valid verified email address, which is bad since the purpose of the feature in the first place is to ensure that all users have valid verified email addresses.
Preliminary research suggest to add some sort of request handler in acct_mgr for POSTs that want to set the email address, and fail if the new address is empty.
