There's about as many opinions on this as there are car owners. I tend to err on the side of caution. I don't do any extreme driving in my new cars until it's had its 500 mile oil change. Then I just drive it like I want to. I've owned 14 brand new cars since 1993, and my 2015 Canyon is the first one to consume any oil. One of the few vehicles I own that doesn't get pushed very hard, because, well...it's not any fun to drive that truck hard. The one car I don't zing to redline on occasion is the one that burns 1/2 a quart in 3,000 miles. Do with that what you will.
One memorable method for me was done by a friend who's had a few Corvettes and a 1998 Camaro SS. He insists that the low-load, to-redline acceleration in 2nd or 3rd gear, followed by a no-brakes, preferably downhill deceleration is key to seating the rings. I can't really speak to the theory behind that.
My opinion is that if you don't really know a ton about how your particular engine is engineered, be nice for the first few hundred miles. Not TOO nice, but somewhat similar to they way you typically drive to work. I can't believe erring on the side of caution would do long-term harm, if any harm at all.
