Why would one try to outhink John M. Browning??
I guess you'll have to ask all the people who have modified the original 1911 design, including the military (1911A1) and Colt (Series 80 Safety.) That would include any other barrel length besides 5", extended safeties, firing pin safeties (whether you agree with them or not...) compensators... the list goes on.
FWIW, I put one in my Springfield standard... about the only thing positive I can say about it is it adds a little weight to the muzzle, on an already heavy pistol. I don't believe it contributes to better (or worse) function, in essence, it does the same thing as the standard setup.
My 4" Kimbers have guide rods because of the spring, and I can see where that probably aids reliability in the shorter pistols. It would really be a trick trying to get that 22# spring shoved back into the frame without the guide rod, too. As someone mentioned, it would be pretty nice to have a captive spring, but then replacements would probably be 3 or 4x the cost of just the spring itself.
