We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.
