Think of it this way. The gear your have now, the rep passives you have now... they completely outgear even the toughest Elite STFs. You don't even need them to crush the Borg or tag bunnies on Romulus. Any bonuses that a PvP rep system gives out will probably be parallels to what we already have and therefore not necessary to push the envelope, because honestly, the envelope doesn't need to be pushed any further.
