So the intent is to dictate to everyone how they build their networks?
Such prefixes would then reach valid lifetime=x, preferred
lifetime=0, be set "deprecated" and not be used for new
connections anymore. Nothing requires connections be killed
using such deprecated addresses.
Get real! If the prefix is not imediately invalidated, it will be
impossible to connect to nodes that now have a valid right to use that
prefix. If the router does not have a current prefix allocation, it must
set valid lifetime to 0. It is not reasonable to expect an automated
process to figure out when you want it to keep a prefix around and when
you want it to go away. Even if it could do that, one set of machines on
the local network may want the opposite state from another set of
machines.
