FWIW, Apple says that’s not even the NN hash function they’ll be using. This one has been buried in iOS since 2019, so it may have been a prototype. Although dumping the NN image seems straightforward, so this seems a faithful copy of that older hash function. (There’s been a suggestion that it’s sensitive to floating point processor implementations, so small hash differences may occur between different CPU architectures.)
