probably because the hardware for bluetooth stacks have gotten crazy small and efficient. I doubt even apple could recreate it without straight up acquiring a company that already can do it.
I'm surprised they didn't use some custom protocol, especially given how bad Bluetooth is, and they control the entire software and hardware stack.
