Automotive, space and defense happily use older processes at scale. Also embedded electronics in all sorts of electronics.

Yes, but that isn't where the increase in demand is. Those things are affected by fabs that could be producing them producing something else, but there will be some stock floating in the system so some resistance to increased prices needed to justify new fab resource, and if things correct a bit in the coming year the maths for a new build might look more dubious. Those with the money to fund a new fab right now are more likely to fund something capable of producing the newer part types. I could be wrong, but the fact that significant new fabs like that are not in progress right now would suggest not.
