I would take the return spring and adjust the tension to how i liked it... true customization

There IS a reason for drive by wire - it's easier to correct a problem (or a perceived problem) with a software adjustment than it is to fiddle with "hardware", which may include replacing actual parts with a corresponding cost in labor. But the downside is that the software engineer's idea of an ideal setup may not match yours.
And, looking at all the trouble Toyota is having with their throttle problem (which now possibly MAY include electronic control problems as well as mechanical ones) does not bode well for the rest of the industry that has also adopted electronic throttle control. Consider: All we have to have is an accelerator Pedal Position Sensor (PPS) that has somehow electronically failed into the WOT position, and the PCM will command the Throttle Position Actuator into the full open position. This COULD, of course be countered by a Brake Sensor that, if activated, tells the PCM to ignore the PPS and close the throttle, regardless of the pedal position.
Since the PCM DOES monitor the brakes, I think, on an ABS equipped vehicle, this seems a change that could easily be accomplished with a PCM flash (software fix).
Probably, it would have been better all along to simply follow the KISS principle.
