Hiding unreachable mount points has the benefits that processes will not get to see relative paths in /proc/$pid/mounts and /proc/$pid/mountstats. Those paths are irrelevant to them anyway; just consider a chroot()ed process that currently sees all sorts of crap. A process that hasn't been chroot()ed will still see all filesystems except the rootfs, so no problem there. Hiding the rootfs by virtue of it being unreachable is actually be a good thing: nobody is actually going to be able to do anything with it anyway; it's just confusing, and adds unnecessary special cases to scripts like mkinitrd. I would actually also prefer to see the hack go that leaves out the slash between pathame components (so "pipe:[439336]" would just become "pipe/[439336]") -- it's good for nothing other than backward compatibility.
