I can imagine a whole host of reasons for needing >1 static IPv6 addresses,

VyOS, because we use a different mechanism for static addresses). I'm
guessing you'd also need static v6 routers, like with IPv4?

It seems invalid for an interface to have both static and dynamic
addresses, and I can't imagine a reason  why one would need it. Disabling
RS and DHCPv6 would also be consistent with static IPv4 support's disabling
DHCPv4, wouldn't it?

I'm not familiar enough with this to have an opinion.

I wasn't going to bug the list with this question until you sent an email
about it, but now that the subject has been breached, I'm quite curious:
Why does a program designed to be a DHCP client have support for static
addresses at all? Seems counter-intuitive.
