We have been progressively obsoleting this for some time in favour of 
sysctl, which covers all of the features you're offering and then some.

Probably the only major advantage your implementation has is the direct 
handling of strings as identifiers, rather than the name-to-oid lookup, 
but the cached OID provides a much faster lookup method for values you 
want to get on a regular basis.
