Sure, but there was never any intention for it to be stable. iptables
can change that library at any time, with no guarentee that any other
apps trying to use it will keep working.

They are defined in the kernel header files. It's a stable ABI, so creating
a local copy is fine (which is what iptables does now... iptables used to
require the presence of the kernel headers).
