> What would be needed is some sort of compatibility switch that disables all optional CPU features. Sure, you will get some reduced performance of the compiled code, but in exchange, a faster startup time.
I think other AOT-compiled languages don't opt in for the lowest set of CPU features -- they just detect them at runtime and use whenever present, all in compiled machine code.
