Pendulums swing back the other way, though, when there's a game-changing advantage to be had. And server software that only has to produce well-formed output to be sent over the wire has considerable leeway in how those well-formed outputs get produced. We've seen that leeway be exploited in a major way at the programming language level, not so much at the OS level and not at all at the hardware level, yet. The question is what hidden advantages one might uncover by doing so.
