I'm building a product that uses the REST API to read and update Shipment Tracking information, and would like to see a couple of action/filter hooks added, specifically:
1. An action hook when shipment tracking data is added/deleted
2. A filter when data is added/updated via the REST API, similar to woocommercerestprepare{$this->posttype}object
