In my not-at-all humble opinion, in an eyeball network, you almost *never* want to make it easier for houses to talk to one another directly; there isn't any "real" traffic there. Just attack traffic.

But creating a solution where you can talk to anyone else on the Internet but not the ones in your own neighborhood is broken, so it needs to be fixed. In IPv4 I've seen this solved with local-proxy-arp within the subnet, and for IPv6 it's easily solvable by not announcing an on-link network so they won't even try to communicate directly with each other but instead everything is routed via the ISP upstream router and then down again to the other customer CPE/computer.
