It's Bjarne (Stroustrup)'s pet feature. You'll notice that many expert practitioners of C++ write std::println("Hello, world"); or similar for a canonical C++ 23 Hello World, but Bjarne pointedly still writes it with std::cout and the iostream operator overloads.

Now that Bjarne is back at Columbia teaching, there's a risk he'll infect impressionable young people with this nonsense, COMSW4995 was not an intro class and I suspect Bjarne's jetsetting makes it impractical to teach such a class, so this risk is small but not zero.
