Why would that make economic sense when the PCB makers already have the necessary machines and I can get a small 2-layer board delivered straight to my desk for a few tens of dollars? Electronic prototypers are not waiting around for some hoped-for long-tail revolution, because it's already possible to click a button in your EDA program and get hardware via fedex almost instantly. And we've had this capability at monotonically decreasing prices for over 20 years.
