Is there a need to lubricate the served string on a compound bow where it contacts the cams?

I am certain that there is a great deal of friction due to the pressure between the cams, strings, idler wheels, etc. With this in mind, is there something that should be added to help reduce wear and promote performance.

We wax our strings to provide lubrication, but the serving is always avoided. I am certain this is to avoid build-up of dirt and to keep the serving in place. However, there is still that contact patch of synthetic string on aluminum. Should it be ignored, or is there a way to properly care for this area?
