Looking at `man 3 exec', argv0 is controlled by the caller and has no connection to the actual name on the disk.

  Well if you can call a syscall you don't need a named file. You can call execfd. One case where I need an executable named temp file is when I need to pass that named file to another process which in turn will call that file (so I don't have control on how that other process will call exec)

I don’t think Apple is going to change that, because I think it causes difficulties for their security/codesigning/sandboxing infrastructure, and I think they don’t see the difficulty and risk of making it work with that as being worth the rather limited benefit
