That's why the privacy extension uses random address suffix for outgoing traffic by default. That has nothing to do with DHCPv6. The only reasons for the latter are:
(1) Your client doesn't support RA-DNS. (2) You want to request a prefix.(3) You need any of the additional fields most people nowadays don't care about. E.g. most computers will just use the NTP pool out of the box.
