Yes, there's non-standardized extensions. But the point was that there are
other implementations of pfkey. And ipsec-tools racoon is an example of
a widely used application that runs in Linux and *BSD using this API. So
for the time being I'd consider having pfkey fixes as a good thing. This
pfkey dumping problem seems to be affecting many users.
