In a greenfield situation that solution could be "compile DHCPv4 for 128 bits" but guess what, we have "legacy" IPv6 systems that aren't compatible with that, and we want results before those systems are all killed off.

Seems to me that adding a routing information option to DHCPv6 solves the problem
without breaking the legacy hosts.

What's wrong with that idea?
