I think the problem can be tackled by implementing this in wireless last-mile networks owned and operated by end users. (Obviously the /64 space is enough to carry that information. Long-range could be done via VPN overlay over the Internet). This will reduce the local chatter for route discovery and remove some of the last-mile load on wired connections, which is in ISPs' interest. I think we'll see some 1-10 GBit/s effective bandwidth in sufficiently small wireless cells. If this scenario plays out, this will inch up to low-end gear like Mikrotik and eventually move to the core. I don't think this will initially happen in the network core for the reasons you mentioned.
