I'm also disheartened by how the man pages for some of the macOS sandboxing commands have declared them deprecated for at least the last five years: https://7402.org/blog/2020/macos-sandboxing-of-folder.html
Is AI a special case? Maybe! I have some ideas about how to do AI sandboxing in a way that works more with the grain of macOS, though god knows when I'll find the time for it!
