Question: why can't the value be changed to 1?

Because some time ago we weren't sure if we needed to reserve another selector
value or not.  Note that some time in future in a product far far away we will
be allowing 0 and 1 for endsystem.  As are routers the restriction about 0 will
still be in force but the one about 1 will be lifted
