Do Anchors Seeking Favorable Terms Align with HBS Study Findings on Traditional Private Equity?

Is it worthwhile or advisable to politely push back on anchors requesting favorable terms with resources we find that suggest that 'In contrast to traditional private equity settings none of the interviewed [for this HBS study] anchors sought fee breaks or other preferential economic terms. Some were attracted by the ability to shape the direction and legal structure of the fund or serve on the LP advisory board?' Mike made mention in a previous AMA that such favorable terms actually don't meaningfully move an LP closer to investment anyways which was interesting.
