For things like Fedora it's probably an "interesting idea, perhaps we
should do it using SELinux" sort of problem, but a config option for a
magic network prctl is also going to be hard to adopt without producing a
good use case - and avoiding that by dumping crap into everyones kernel
fast paths isn't a good idea either.
