The problem with this is that a number of sysctl's aren't just "read"

first then copies the results out to userland.  Common examples are
things that follow linked lists in the kernel, but then present a nice
simple array (often nice 64-bit alignment friendly structures instead of
"raw" structures used in the original data) to userland.

...or, like my current pet project, collating per-cpu copies of network protocol stats.
