Anecdote: Last year my girlfriend recently became obsessed with BBQ and has been smoking brisket using technique #4 for the past month. It's consistently improved the brisket every time.
McDonald's used to fry their fries in a 93% tallow oil blend until they stopped in 1990 because of hysteria over cholesterol in beef fat.
Guess nobody considered the patties were still chock full of (much more) beef fat, but oh well. (Properly deep fried fries retain only a few grams of oil vs upwards of about 500% more in a single, lean McDonald's patty.)
