I think it should join "billion" in never being ever used again due to its ambiguity.
Does it mean something other than 1,000,000,000?
EDIT: Apparently in some cultures, it means a million million, ie, 1,000,000,000,000, or what most people would call "trillion".
So all that accomplishes is conflating thousand with million with billion. (Of course "million" is already a conflation of "thousand"!)
