I'd argue that move semantics is strictly superior to value semantics. But more importantly, my point is that in a world where pretty much all modern languages except Go have pointer semantics by default, and when you language needs to have move semantics for memory safety in many cases, having yet another alien (to most developers) behavior is really pushing the complexity bar up for no particular gains.
