And this only refers to unix socket indeed, really we can deprecate
this.

Back to what I said for Nice/Scheduler, I'm not so sure about removing
them.  Actually I remember this was useful when I was testing long
time ago.

Basically what I observed is that RT scheduler + process pinning to
spare CPU makes Netlink reliable (no event message loss). And that is
good to have in place under high load, otherwise nodes get out of
sync.
