I believe this is because the Linux /proc goodies are mostly
cute hacks to turn netstat, etc., into kernel modules.
Having dealt with programs that parse the output of GDB, and
Hewlett-Packard emulators, I declare it categorically insane
to base a long-term interface on something that prints human
readable messages which are then parsed by programs.
I am in favor of beefing up /kern, but it must be done in a
machine-readable way; the current output of sysctl -a, or
mixerctl/audioctl, is not too bad, actually. (See also environ(7).)
