This isn't happening anything soon, the diversity between the dt members is what makes the system interesting and less centralized. If this was to be the case then the system won't be as decentralized (to some extent as theymos had intended).  I'll go with @ThePharmacist reasoning on this as farming of account (back when it was still ok to do so), was mainly done for one reason, which was to join a signature campaign but currently, farming of accounts are done for various untrustworthy reasons which includes; farming trust, farming merit, scamming and obviously cheating signature campaigns.

When you consider this recent development toward account farming, you'll understand why there's an unwritten rule towards discouraging it. Using your common sense, If a new rule is passed, you don't go punishing old offenders that commited that offense when it was not yet a crime.
