Yeah there is: not breaking all your internal traffic when the wan link goes down and you lose your prefix.

I can potentially see that scenario if your transit provider is giving you a dynamic prefix but I've never seen that in practice. The address space is so enormous there is no reason to.

Otherwise with either of RADVD or DHCPv6 the local routers should still be able to handle the traffic.

My home internal network (v6, SLAAC) with all publicly routeable addresses doesn't break if I unplug my modem.

IIRC, there are some sloppy ISPs who are needlessly handing out prefixes dynamically. ISPs seem to be doing everything they can to fuck this up, and it seems more incompetence than malice. They are hurting themselves with this more than anybody else.
