That makes sense to me, it keeps the same name but makes it a distinct type. This is also somewhat interesting that we could potentially use it as an overloadable parameter in helpers. Like dynamic dispatch based on whether or not the size is completely known at runtime. This would probably require that LLVM vscale vectors codegen fine on architectures without them, but I don't know the full extent of that.
