Oh you don't need namespaces to hork mtab. Do a mount from a chroot environment. Or try to use --bind or --move mounts (at all) and watch it beg for mercy. (I accidentally ran UserMode Linux as root once, using a hostfs root filesystem to borrow the existing Linux's root filesystem, and its' mounts edited the parent system's /etc/mtab. Yeah, that was user error on my part, but it's also the _only_ gotcha I've found when doing that.)
/etc/mtab is simply brittle. Personally, on systems I build, I ln -s /proc/mounts /etc/mtab
