keep the spring if you want as you have done in the last 20 years or more. your hobby do as you wish. but there are better ways to do things.
I use to disconnect the throttle springs then I learned the error of my ways. I learned a better way and now leave them in place.
The extra power required (both servo torque and electrical) to hold the throttle in place against the spring tension is very minimal.
