Do not know the exact answer to your question, but I can make some assumptions.
1) The 6.0L has the HFCM filter on the frame rail as it is the low-point of the fuel delivery system... so water and sediment would settle or want to settle at this point. Water is heavier than fuel... so water settles to the bottom.
2) The 6.0L requires 2 filters due to the extra fuel presures and the need for better filtered fuel... so space and accesibility is an issue... one on the frame rail and the secondary on top of the motor.
3) The 7.3L, even though eiser to change and open the drain valve... allowed fuel to spill down the side of the motor... which is both a safety problem if the motor is hot and/or an environmental problem when people drain and allow fuel to just flow onto the ground (no room for a catch pan).
My son drives a 7.3L and I drive a 6.0L... so I know exactly what you mean.
I have the replacement 6.0L HFCM drain plug you referenced above which is a special order item and allows the use of an adjustable wrench, allen wrench or even hand tighten to open and close (to turn the large knob). If your dealer can not find it right away... tell him that it is "Blue Oval" part and used on medium duty Ford trucks... it's a different parts database than the standard truck/car parts database the delaer normally is using.
