The kernel has far more compelling reasons to turn things into modules
though, since very far from every system is directly connected to a
token ring network, or hooked up to an atomic clock via the parallell
port or similar weird things that Linux supports but that is pretty
unusual.

Possibly, but then we'd have collaboration issues between core coders and
module hackers instead, and new modules would need some way of getting
included that doesn't interfere with other modules.

Since worker processes is intended to be the new default way of running
checks, everything that that functionality relies on must ofcourse also
be in the core. The fact that it makes life easier for a ton of modules
is just a happy accident, really.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
