That's an interesting solution. Would also not be unreasonable for like indexed loads/stores, though there fully getting rid of the built-into-instruction element type would have its problems. While vrgatherei32 is certainly definable, it not existing does have the benefit of not burdening small impls with yet more connections for indices. Also, vrgatherei64, spooky.
