Code bloat was the other reason... I suspect that people that are
that tight on space (and there are several that use FreeBSD where an
extra 24k is a big deal) will likely invent a kernel option to compile
them out. However, there are a number of areas in the kernel that
we're free and loose with the code bloat wrt error messages and the
like.
