As noted this is to minimize the chances of stray RF generated by vibration of metal to metal connectors, affecting the RC system. Many years ago this was a well know cause of mystery crashs but as radio systems got better i.e. FM, PCM, 2.4 and etcera the fellows tended to forget this. Now when spark ignition engines agine came along this became more important.
Just remember, if the throttle arm on the engine is metal do not use an S bend or metal clevis, not even a metal pinned plastic clevis. If the engine throttle arm is plastic S bend, metal clevis or metal pinned plastic clevis are OK to use. Agine no metal to metal contact at the engines throttle arm.
