On top of that we shouldn’t distribute compiled binaries for the x86 and ia64 chipsets; instead program code should be distributed like .wasm, in a hardware-independent way, and compiled on the target device. That would enable that hardware can use any chipset it wants and there are no software incompatibilities because of it.

You’re describing Gentoo Linux . . . which is not especially popular among Linux distributions even though it runs on just about anything. There may be a reason for that.
