Héhé, I'm fully aware of the limitations, we move step by step but feel free to
send a patch ;-)
More seriously, I'm thinking to that problem but I did not start anything right
now and I don't know when I will have time to do it.
If I understand well, you are saying that this missing part is blocker to use
the new socket option. I don't agree with this. Doing a dump in an another netns
is easy to do.

I don't understand why dumping in another netns is a problem.
