The responder might not be able to initiate a reauthentication (depends
on the config, e.g. whether EAP or virtual IPs are used).

No, as documented , clients will schedule a rekeying if an
AUTH_LIFETIME notify is received even if reauthentication is disabled in
the config. There is currently no option to change that. So you'd have
to modify the code to make the client ignore any received AUTH_LIFETIME
