Linux posix_spawn is a wrapper around clone and exec. There is no primitive on Linux to create an entirely blank process. This is adequately discussed in the linked LWN post.
Other operating systems either have parallel APIs to fork (e.g. the posix_spawn syscall on macOS) or do not provide fork at all (Windows).
You seem to persist in reading into my words claims that aren't there and then excitedly debunking them. I feel I'm extraneous to this process, though, so I think I'll let you carry on arguing with the guy in your head on your own terms. It's more fun for both of us.
