There isn't a "vast install base" of firewalls (border routers). If there was we would have 99% IPv6 traffic instead of 1.6% IPv6 traffic. The key is to get the functionality into firewalls/load balancer etc. ASAP. Hosts can happen as they are replaced as part of normal refresh cycles or apps can use raw sockets if they need the functionality sooner. The IPv6 layer will fragment the raw packets with the hop-by-hop header fine.
