agreed that we'd be better off without that impediment.  but the A6 method 
of removing that impediment creates impediments of its own, and some folks 
believe it's not a good tradeoff.  and it's hard to understand the value 
of A6 (to understand whether it is worth the cost) without having a good 
understanding of the total cost of renumbering.
