The objective of Part M Subpart G is for the operator (the AOC holder in the case of a commercial operator) to exercise independent oversight of the maintenance organization. The person or persons responsible for the oversight functions cannot be employed by the contracted maintenance organization. Continuing airworthiness functions such as record keeping, planning, technical services etc. can be included in the maintenance contract, but the operator/owner is responsible for airworthiness.
It would appear that a whole new breed of specialist companies is about to arrive on the scene.
