You know more than I. Jones NCTI taught us we bond to the common ground of the residence. The drop point (or whatever you may call it) being where the wall box enclosure holds the ground block ect. Regardless, if we don't bond, or ground, if something happens, the liability for not doing so is tremendous. I've seen too much melted cable and hardware to believe it's un necessary. $100.00 automatic chargeback with Brighthouse for not doing it.
