Isn't the former actually "control all addresses in use and accept that
clients without DHCPv6 are forever lost to us"?

Good point; based on what I've spent the day doing, I suspect "normal"
is something we're very far from...
On a more general note, we've always managed clients IPv4 address/DNS
entries quite closely; we've not done that with IPv6 and noticed no ill
effects, and given the growing domination of wireless/BYOD, I wonder if
those days aren't coming to a close entirely.
