Elevator achieves performance on par with or better than QEMU's user-mode JIT emulation.

QEMU is a weird pick here. Why not FEX?

Why is it "weird"? It has been around much longer AFAIK.

Because fex/box86 have the ability to run arm binaries linked to x86 libraries, netting signficantly greater performance. In addition to other tricks.
