There are concerns about that approach. Presumably there are nutjobs that
want to have kernels absolutely free from the imperfections of the past. In
addition there are cases where a facility has enough overhead to justify
modularizing it. In some cases hooking code/data in at runtime with low
overhead, at random points in the kernel, and without bugs, is very tricky.
