[ArrayBoundCheck]

Having slightly better optimizations due to changing ABI doesn't sound worth the friction of having another language in the codebase. Especially when the guys who invented it (google) is famous for sunsetting things and couldn't get their peers to use bazel, the other thing google invented

I don't care if this sounds uncharitable, I see the pitfalls and I seen so many people get sucked in to prior pitfalls
