Renumbering is not as smooth -- it appears to be impossible to remove
a set of addresses wholesale, retracting a set of PIOs merely causes the
old addresses to become deprecated. Since after a

Actually RFC 6204 (and its successor 7084) have a requirement that enforces
keeping it in the RA for at least 2h. HNCP makes following 7084 mandatory
atm.
If you're referring to RFC 7084's:
L-13: If the delegated prefix changes, i.e., the current prefix is
replaced with a new
If you're referring to RFC 7084's:
L-13: If the delegated prefix changes, i.e., the current prefix is
replaced with a new prefix without any overlapping time
period, then the IPv6 CE router MUST immediately advertise the
old prefix with a Preferred Lifetime
Why don't you set the valid lifetime to 0 as well?
If a new host is connecting to the network while you're advertising the
max(old valid lft, 2h) valid lifetime, it will actually auto-configure
itself with an address from the withdrawn prefix. If you set valid
lifetime to 0, it won't.

In an ungraceful case (flash renumbering) we stop announcing the prefix in
HNCP and the individual routers who have assigned it, MUST deprecate it
according to RFC 7084 (not just stop announcing it in RAs). This deprecation
sets preferred lifetime to 0 and valid lifetime to max
