Where do you get that? Those have all been used in kernels, they work.

Also on another front Apple seems to have already enabled device drivers in user space: https://developer.apple.com/system-extensions/

Yes, you can use them to play around and experiment with OS-level stuff and even have some fun with it.

But you definitely cannot build a performant and robust kernel from scrtach with these languages.

I think this is irrelevant (and less importantly, false). Its's fine to use eg se4l as a foundation, or as a incremental step even just have a safety focused driver runtime inside the kernel proper.
