If you mean doing it in setup_mountpoint(), then because (ignoring the name) setup_mountpoint did not assume that $mountpoint is a mount point thus is can still be called on a simple dir and also doing --make-private right before umount is more fail proof and lets propagation happen in the default way before umounts.
