>That, and basically guaranteeing you don't have to deal with the company you just acquired having deployed their accounts with the same 10/16 subnet your own company uses.
I always found that to be a desperate talking point. 'Prepare your network for the incredibly rare event where you intend to integrate directly' (didn't anyone hear of network segmentation?). It makes a lot more sense to worry about the ISP unilaterally changing your prefix - something that can only happen in IPv6.

ISPs unilaterally change your DHCP address on IPv4 all the time. And in any situation where you would have a static address for IPv4, your ISP should have no problem giving you a static v6 prefix. This argument makes no sense at all.
