In think the reason you can’t use metal is because building code is significantly more lenient for wood structures. As soon as you bring metal into the mix you get stuck with more complicated engineering and permits
It's coming. There's plenty of engineering experience framing with metal, Light Gauge Steel (LGS) framing has been around for decades. This is just adding a new use case.
Yeah I get that steel is a better material in many cases but building code is going to be slow to catch up, or wood simply has a grandfather clause that makes things simpler
