Every time the price of fuel climbs, someone new will rediscover this bit of aeronautical truth. A F/E at United got a nice bonus for suggesting this back in 1963.
And swept-wing aircraft with center-section fuel (i.e. tank well fwd of the CG) are almost always best managed if the center tank is burned off first.
BTW: this can only be true if the stab has negative lift (decalage). If anyone knows of an aircraft for which this is NOT true (a canard for example) then the aft CG/reduced drag paradigm will not apply.
