[ipv6hackers] Question on DHCPv6 address assignment

Yes, I believe it works just like DHCP for IPv4 in that respect.
However, each DHCPv6 server could be configured for different behavior for
lease times, renewals, etc.
The ICMPv6 RA message would dictate that the clients perform stateful
address assignment (DHCPv6), but a host could choose to ignore that
recommendation and proceed with a static IPv6 address.
That is why DAD is important in all cases prior to assuming use of an IPv6

Same thing after boot-strapping? i.e., last-used address is renewed as
opposed to getting a new randomized address?
