Ha ha, I think the busybox rm implementation also doesn't have it, be careful, it's present in lightweight containers, even though it's probably a recent thing. Can't speak for MacOS too.

TBF, this safeguard has never saved me, being careful saved me. You can afford to take the time to be careful, because writing the powershell equivalent is probably at least ten times longer (just kidding, or am I?), and clicking buttons in the file explorer is a hundred times longer. Always write the "-rf" after writing the path! I never run rsync without a dry-run, too, even without --delete.
