A reasonable alternative would be to properly assemble the raceway.
I take offense to the implication that I would do anything less than that. For the record, I double check EVERY SINGLE set screw TWICE. I tighten as I go and then go over my raceway a second time EVERY SINGLE TIME giving EVERY set-screw a second crank with a flat-head because I feel it provides more torque and as a means to double check my own work because I am only human.
You can assemble the raceway PERFECTLY... that doesn't stop people from putting their feet up on it, sitting on it, HANGING BENDERS ON IT, or prevent loosening over time due to vibrations and such, etc.
The simple fact of the matter is, if that raceway comes apart FOR WHATEVER REASON, you've lost your ground fault current path... and that wire-type EGC that maintains that ground fault pathway when a piece of pipe is hanging out of connector might just save a life.
Therefore, there IS a practical purpose behind a wire-type EGC in a metal raceway.
