The advantage is that the API is now the same for IPv4 and IPv6: it's all nm_dhcp_config_*() and we can (easier) treat the address family generically. We still need two distinct GObject types, mainly because of the glue code for exposing the object on D-Bus as NMDBusObject. Of course, that could be solved differently, but as it is, it's quite nice.
