Because ofwdump already exists for that.

Also, the ofw tree lets you do such crazy things as open, close, read,
write, and seek on them which is kinda hard to do to on a sysctl node
(and much easier on an FS).

The only problem right now is that pseudofs doesn't let you open/etc
directories.  If we want to support this either we have to stick a nasty
file in the tree for EVERY node, or fix pseudofs to support opening
directories (which I think SHOULD work since the VFS layer has it's on
READDIR and doesn't need to open it like FFS).
