I don't know that this counts a a strike against /kern and /proc,
since I would never propose giving these up, anyway. It's handy to
be able to look at any variable in the kernel one wants to. (Although
once a Linux fellow seemed to be claiming that you can indeed get
the value of and change any global kernel variable through their
/kern filesystem.)

Would it bloat terribly if we included the ability to do both in
these utilities (or #ifdef'd them)? I'm sure that there are people
out there regularly recompiling kernels that don't have the time
and space to do the whole userland too who would be happy to have
a userland that didn't need updates so often.
