That's what I thought, considering the scratches and gouges I see on my aluminum and steel racks after a few months of use.
My personal view is that CF is not an ideal rack fabrication material, for many of the reasons you stated plus others. If you want to install bags on a CF frame, I think a soft bag is a much better solution than rack and panniers. Offerings from bikepacking gear providers and others are available for that purpose.
