On point, Bing.
The DSA team did a thorough job investigating this situation and their report reads clearly. It's not their job to implement corrective actions however, and the results of their work leave a challenging situation for the user, the regulatory authorities, and to some extent, perhaps the manufacturer.
Para 1.4.144/5 Maneuver Limits ought to raise the attention level of anyone involved in certification testing. Not pointing a finger at Bell. Users use, and stuff happens. I recall clearly the day when our CH-53A Project Pilot returned from a visit to the USMC MAWTS Squadron at Yuma, where they were teaching squadron pilots on how to use the maneuverability of the 53 to avoid enemy aircraft. He knew that our flight loads survey data didn't include what was going on there. Not close. Fixing that took some doing.
