ISC dhclient **only** does DHCPv6. It doesn't handle any RA recieved
inforamtion such as prefixes, not will it generate any routes.
AFAIK, no patches for it do either - instead a 3rd party will do this.
NetworkManager, systemd, Linux kernel (if dhcpcd hasn't turned that off).

So what you say about dhclient not receiving SLAAC addressess makes
perfect sense.

dhcpcd is the only all-in-one solution :)
