There's been plenty of foot shooting in the past with private and
non-allocated address space. Why is this time going to be any
different? Giving away more address space with RFC1918's properties
will only provide a level of legitimacy to further foot shooting -
people will ignore what this space is specifically for because by its
nature it can't be policed - I'm guessing the Hamachi people
will start using it straight away since they "lost" 5/8. If this /10
never exists, then whenever people try to shoot themselves in the foot
they'll unavoidably know they're about to do it. Of course you can't
prevent stupidity, but you can make it more obvious that it is
