If Mark wants to do that on his network, he can. That doesn't mean that you have to.
I show it not so easy.
No, you've shown that there are ways to do things differently than using static addresses for your services.

If you're talking clients (system using only outbound connections) then they will renumber with SLAAC+DHCPv6 the same way that IPv4 clients renumber with DHCP now.
If you're talking about services (with inbound connections) then yes, IF you ever have to renumber, AND you use static addresses instead of SLAAC, you'll have to do them by hand.
But weren't you just arguing that dynamic addresses for services is a bad thing? Which way do you want it? Because you can have it either way. In fact, you can have it BOTH ways if you want it, depending on the service. I find static addresses for services easier myself, but Mark is a lot smarter than I am, so I'm perfectly ready to be proven wrong.
Meanwhile, the thing that most people miss about IPv6 is that except in edge cases, you never have to renumber. You get a massive address block that you can use as long as you pay your bill. The chance that you'll have to renumber, ever, is incredibly small.
So, again, stop spreading FUD. Doug
