Kldloading mac_bsdextended, I don't have this sysctl and the man syntax looks good to me.

Is it possible we can get the commit message saying when this sysctl was removed? I see the sysctl existing 19 years ago in 56c38cd967.

after looking at the code, I'm wondering - that sysctl is still in the code but it really just sits there as the man page suggests. Maybe we should clean up the module first?

Or maybe I'm reading this wrong? Don't want to jump to conclusions.
