Generally I'd prefer that resetting stats wasn't available as players incorrectly become newbies and that causes problems with the score. However if it was removed people would recreate accounts. We can't prevent people recreating accounts as it's almost impossible to enforce and there's legitimate reasons to recreate accounts (eg stalkers!).

Therefore, allowing partial resetting of scores have no real benefit IMO. It also would encourage people to try and get the "perfect score" which is something that should be discouraged.
