Well, there are two factors that go into the recommendations. As you mentioned, one is adequate micronutrients. The other is chronic disease risk reduction. The 5-10% of total calories from saturated fat recommendation falls into the latter category. The risk of meat and dairy is not just cancer, but saturated fat.

I would agree that with proper knowledge and planning, it's possible to reduce carbs and increase protein/unsaturated fats while maintaining adequate fiber and micronutrients. But in practice, I think it's much more common to see people taking low-carb diet recommendations as a license to eat a pound or more of meat per day, drink gallons of milk per week, and completely ignore fiber intake, which is objectively not healthy.
