Kjay:
We may be talking about two or more different scenarios here. For a new structure, no the EC is not responsible to do the bonding, only to install the 250.94 block.
On service changes reconnecting the LV bonding to the upgraded grounding and bonding system, for any existing data/comm/sat etc. This has been a 'standard' practice for the most part by the EC's. IMHO, the liability issue would be greater if the bonds were not re-connected after a service change.
