4-speed pedals Heavy Duty

Im not getting my head around why this spring is removed? I can see where it may not be needed. Thus just wasted push needs. But I have read some posts that it can hurt the clutch?
In a nutshell:
If you have a 3 finger B&B clutch, you keep the spring.
If you go to a diaphragm clutch, you remove the spring.
I went to a diaphragm clutch, and removed the spring...Butter. :thumbsup:
