Thank you, Brandon, this is the guy whom I heard it from.
And if you run 2 layers of aluminum tape, that is more weight on your car, and I don't think you would want more weight underneath your servo, maybe on the centerline or in the rear, but not under your servo, it is already heavier than the esc ad reciever in most cases.

If you read quite a few pages back, Jason from BMI stated that running a chassis with a large area in which the center of the graphite it exposed can cause interference especially with cheaper radio gear. That is why BMI doesn't mill down the area under the servo since lowering it 0.5mm doesn't make a noticeable differance compared to the cost of possible glitching.
