This is a case where one is best 'controlling' this via policy, not
mechanism, in my opinion. This sort of arbitrary technical limitation
tends to be foolish and often bites someone somewhere down the line.
I'm sure you just wanted to note how it could be done, not recommend
that it should be done, but I thought it should be made clear. I
wouldn't recommend that anyone do this unless there is an extremely
good reason for it.
