BTW, I took a look at ipv6 and unlike ipv4 there seems to be no sanity
checks or per-protocol booleans indicating proper netns support.

Is my interpretation right that ipv6 just assumes all registered
protocols are netns aware at this point?

If so that was definitely a bug, because things like l2tp have an
ipv6 component and were not fully netns aware until very recently.
