How? We don't let the dynamic linker open arbitrary files for writing using the current processes' permissions because the current processes' permissions might be system-wide.
This looks like a thing that Apple thought was cool in-house, someone had a brainwave and said "wouldn't this be cool for our developers", and it got included.
It wouldn't have got into any of the proper BSDs, I tell you that much.
