The definition you propose will not work for this document for at least the
following two reasons:

   - A host that is IPv6-only by your proposed definition cannot implement
   DHCPv4, because DHCPv4 requires sending and receiving IPv4 packets.
   - In section 3 draft explains that the client can decide that only
   certain interfaces are IPv6-only. This means it could be using IPv4 on
   other interfaces, and it would not meet your proposed definition.
