More likely than not, those address advertisements have a

You continue to ignore the fact that when the connection to the public
network reestablishes with a different prefix, all existing internal
connections will be dropped. [...]
Not so. (If you build your system in an optimal fashion -- which really
does need a bit fleshing out, though.)
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.
