I was of the impression that there was a draft or similar for
single-topology (IPv4+IPv6) OSPF.  Did anything ever come of that?

Juniper support IPv4 families ("realms") in OSPFv3.

Problem for an ISP (OSPFv3 with AFs): if v6 breaks, v4 breaks too since OSPFv3 runs over v6 (even when carrying v4 AF)? Better with separate OSPFv2 and v3 instances.
