> just running that on 28nm without any changes is not possible?

From what I understand, "node" in this context doesn't look like a printer resolution, it looks like a lego kit of transistors and such that TSMC has tuned to use the layer heights / counts / materials they plan to deposit. Since these details change between nodes, the 2D shapes aren't portable. You have to swap components.
